Frequently Asked Questions

  • A/C Compressor

  • Car Air-Conditioners:

    • The invention of automotive air-conditioners has transformed the vehicle cabins from oven conditions to comfortable ones during the traveling in hot seasons.
    • Vapor-compression systems are still the most widely used type of automotive cooling systems despite their high energy consumption and negative environmental effects.
    • Conventional compressors are powered by an engine’s belt drive.
    • However, Electric vehicles do not have belt-driven engines, therefore a different kind of compressor is required.
    • If the A/C fails in a ‘normal’ car, you can still drive and simply open a window.
    • But if the A/C fails in an electric vehicle, the car will not run, as it’s a safety risk, the battery will get too hot.

    Compressor:

    • The air compressor is the heart of an A/C system.
    • Without one, you’re left with simple blowing fans that do nothing more than suck the outside air and its atmospheric temperatures into your vehicle.
    • The air compressor itself is powered by the serpentine belt. If the belt snaps, the A/C system won’t function, but neither will the car itself.
    • But the electric compressor operates independently of the engine.
    • The compressor is always driven by the electric motor, so when the hybrid or electric engine isn’t on, the eCompressor can still operate.
    • This offers a significant advantage over traditionally fuelled vehicles as it maintains a cool temperature in the cabin.
    But it is unfortunate that the OEM air conditioner does not last forever. It stops working after a certain period. Especially, the compressors of our air conditioners get damaged. Signs of an ailing compressor include strange noises, fluid leaks,(not in e-compressors) and inconsistent operability. It is not an easy job to find a great AC compressor from the market as there is a bunch of low-quality manufacturers out there.

  • Motors

  • What is a winch? In what Way It Differs From a Hoist?

    A winch is designed to pull things that are either on a flat surface or on a very small hill. If you need something to pull, for example, a tractor out of a hole, you need a hoist. A hoist will have extra braking for the safety of both your pulled object and you.

    The motor -The power:

    If the winch is electrical, it will need an electrical power supply. Since winches don’t pull a lot of currents, they can pretty easily be operated by hooking them up to your car.

    Selecting the motive power:

    What Motor Is The Best Motor To Use For A Winch, And Why? The 3 types of motors are
    • Electric -Stationary applications, most of the time can obtain power from the main grid, also on ships, the electric power sources become more and more powerful, so an electric motor would be the right choice.
    • Hydraulic- Mobile applications like earth moving machines, piling equipment, and mobile cranes normally have a hydraulic power source, they don‘t carry high power compressors or generators. For these applications, a hydraulic motor is selected.
    • Pneumatic- Then we have the so-called hazardous environments, where explosions might occur, think of exploitation of natural sources, mining, and offshore oil and gas. Air motors are very common in these fields.
    The choice for the right motor depends mainly on the available power source.

    Product Selection:

    Buyers can select industrial winches by Type of winch, Type of gear, Winch size, Drum size, Line type, Brake type, Performance specifications, Power options, Duty cycle, Product options, and additional features.

    Types of Winches:

    There are several types of winches available to suit user needs.
    • Capstan winches
    • Friction winches
    • Hand winches
    • Theater winches
    • Utility winches

    Applications:

    Industrial winches are used in a variety of areas, including:
    • Automotive
    • Construction
    • Industrial
    • Military
    • Marine
    • Mining
    • Railroad
    • Recovery
    • Oilfield
    If you don’t know what pulling capacity you will need, multiply your vehicle’s gross weight by 1.5 to get the ideal pulling power for your vehicle. Ex: To pull an 8,000 lbs Jeep, your winch capacity should be a minimum of 12,000 lbs. Check the buying guide below for more on this. Gross Vehicle Weight= Vehicle + Passengers + Baggages Weight

    Winch Brands:

    It’s very difficult to select the right winch brands as there a lot of companies that produce winches. However, some leading brands of winches that offer high-quality winches are Warn winch motor, Smittybilt motor, Badland motor, X Bull motor, Superwinch motors, Ramsey and Mile Marker motors, etc. They are highly trusted in the offroad community.


  • Heavy Duty Trucks

  • Truck Alternator:

    For goods transport, long driving periods are always there on the agenda. Safety, comfort and a wide variety of functions are therefore of great importance. Whether it is a medium or heavy range of Trucks, the range of electrical equipment is also wide. So more powerful alternators for commercial vehicles to safely supply power to the many electrical devices in the vehicle is important. The starter is an unsung hero of a vehicle's electrical system. Often ignored and hidden well out of sight, a bad starter can mean a lousy start to the day in most cases. If turning the ignition key returns the clicking sound of a starter solenoid instead of healthy engine rotation, the starter may be the reason.

    What Is A Truck Alternator?

    Truck Alternator is a generator of electric power in a truck and is a significant component of the vehicle's charging system. When an engine is running, the truck alternator charges the battery and supplies additional electric power for the vehicle’s electrical systems. Making sure that the electrical system of your vehicle will function accordingly, you should know how to choose the right high output alternator.

    Possible Culprits If Your Vehicle Doesn’t Start:

    When your truck, semi or any vehicle doesn’t start (especially in the cold), many possible problems might go through your mind. Don’t panic. a checklist of possible culprits for you to inspect when your vehicle doesn’t start.
    • Battery
    • Alternator
    • Starter

    Components of the Heavy-duty Electrical System:

    The heavy-duty electrical system is made up of the starting system and the charging system. These systems are, in turn, comprised of batteries, the starter, the alternator, the interconnecting wiring, and electrical and mechanical switches. For maximum operating efficiency, all parts of the system must be functioning properly. Commercial-vehicle starters must withstand a lot of motion and frictional resistance from the engine and auxiliary units. So Powerful and efficient high-quality starters and Alternator with high reliability and long service life and for on-and-off-highway commercial vehicles are what needed.
    • There is a range of alternators, starter motors, and components that will suit anything from a small engine vehicle through to the largest of mining dump trucks.

  • Components

  • Alternator Regulator:

    What Does An Alternator Regulator Do?

    • It supplies current to the rotating part of the alternator.
    • Simple alternators are originally electromechanical devices that switched the field current on and off to control the output voltage of a regulator.
    • Today’s alternator regulators are semiconductor based and the most sophisticated are controlled by embedded computer chips, and they are all externally mounted.

    The Voltage Regulator:

    • It limits the maximum voltage in the electrical system.
    • With regulators for the alternator system, voltage limiting is the means of controlling output.
    • If the alternator was allowed to constantly produce all the power it could, system voltage would rise to a damaging level, the battery would overcharge, components would be damaged, and the alternator would soon overheat and burn out.
    • Electronic voltage regulators have replaced the old vibrating point type regulator, and electronic regulators react even faster.
    • With a modern electronic voltage regulator, the voltage at the system will be very consistent.
    The battery serves as a big cushion in the system, which also smoothes out voltage levels. The battery prevents major and sudden voltage changes in the system.

    The Distributor:

    • It handles several jobs. Its first job is to distribute the high voltage from the coil to the correct cylinder.
    • The distributor is the component that transfers the voltage from the ignition coil to the spark plugs. The distributor is driven by the engine's camshaft.

    Modern Ignition Systems:

    Newer ignition systems do not have distributors. They have multiple ignition coils, each dedicated to a spark plug or one ignition coil for two spark plugs. The Engine Control Unit (ECU) controls the ignition system.
    • OEX, Bosch, Delco-Remy, Denso, Prestolite, Mitsubishi Electric, Valeo, Magna, Continental, Faurecia, Ford. Mitsuba, Hitachi, Nikko Electric, Lucas, and Iskra are some of the leading brands which you can purchase from your local dealer.


  • Forklift

  • Forklift:

    Starting an industrial vehicle is really not possible without a properly working starter motor. you won’t be able to start your reach truck or forklift at all if the starter motor does not work. To solve the problem, the replacement of the forklift engine part is the solution.

    What is the work of as Starter and an Alternator on a Forklift?

    The starter is an electric motor needed to turn over the engine to start it. An alternator is part of the charging system on a forklift that powers accessories on the forklift.

    Different starter types:

    • DD Direct Drive
    • PMGR Permanent Magnet - Gear Reduction
    • PMDD Permanent Magnet - Direct Drive
    • OSGR Off Set Gear Reduction

    Important things to know when ordering a Forklift Alternator:

    • Ordering by part number is the easiest way to go.
    • Ordering by part number is the easiest way to go.
    • The connector type is really important--if you don't have the right connector type it's very hard to install in the field.
    • The amperage of the alternator is important. You can use a higher rated alternator but you shouldn't replace an alternator with a lower amp rating.

    Things you need to know when ordering a new forklift starter:

  • Small Engine

  • Small engines:

    • In small engines, the engines are small in both physical dimensions and power output, relative to larger automobile engines.
    • Their Power outputs are typically less than 11 kW (15 hp).
    • The smallest of all are used in handheld garden machineries, such as string trimmers and chainsaws.
    • Production cost is often a key consideration for small engines, resulting in relatively simple designs (compared with automotive engines, for example).
    • The most common configuration is a single-cylinder engine that is air-cooled.
    • The combustion cycle can be either two-stroke (which results in a lighter engine for given power output)] or four-stroke (which produce lower levels of exhaust gas emissions). The fuel is usually either petrol or diesel.

    Design:

    Electric starting, which has become more common over time, requires a more complex electrical system. These engines also require a starter motor, a battery to power it and an alternator to keep a battery charged. Small engines can have the crankshaft oriented either horizontally or vertically, according to the intended application. Vertical axis engines were originally developed for rotary lawnmowers, but the size of this large market has encouraged supply of cheap engines and they are now also used for other purposes such as generators

    Motor Starter Varieties:

    Four particular varieties of motor starters are: Across-The-Line, the Reversing Starter, the Multispeed Starter, and the Reduced Voltage Starter.

    Manufacturers:

    The six largest manufacturers of small engines for power equipment were Honda, Briggs & Stratton, Kohler, Generac, Subaru, and Kawasaki.


  • Power Sports

  • Powersports:

    Powersports stands out with consumers for its ability to offer fun, utility and outdoor recreation. In fact, vehicles that can straddle the line between utility and sport seem to be popular in most segments of the Powersports industry.

    Examples of Powersports Vehicles:

    Motorcycles, ATVs, also known as a Quad (bike), Three-wheeler, Four-track, Four-wheeler, or Quadricycle Snowmobiles and PWCs, a Personal watercraft (PWC), also called Water scooter, and comically a Boatercycle.

    Don’t let Your Faulty Starter Prevent You From Your Desired Trip!

    No matter how powerful the engine or strong the suspension of your Powersports vehicle, you still won’t be able to enjoy the freedom of conquering a trail or track if your starter isn’t working properly. If you smell smoke or hear grinding noise when starting the engine, or your engine is not turning over, there’s a huge likelihood your starter is nonfunctional.

    Do Side-by-Sides Have Alternators?

    Most side-by-sides, as well as, ATVs do not use alternators, instead, they have ‘stators’ that use a magneto-based charging system that is integrated into the flywheel of the vehicle which helps maintain battery charge. The stator generates and then maintains a charge to power whatever is currently running and nothing more. Alternators can help recharge the battery, however, stators just maintain the current battery charge. That is why often after long periods of not using your side-by-side you may find that the battery is dead.

    Why Don’t Most UTVs Have Alternators?

    • In order for an alternator to work it needs a steady amount of airflow to cool them down.
    • However, due to the adventurous nature of side-by-sides, most alternators cannot handle the amount of water, mud, sand, and other debris that UTVs encounter, rendering them useless to the vehicle.
    • So because of the debris that our vehicles are constantly coming into contact with, alternators just cannot be put into our side-by-sides.

    Then What Do The Side-by-Sides, As Well As ATVs Use?

    However many side-by-sides, as well as ATVs, use a “magneto-based” charging system for the battery of the vehicle. Everything works the exact same as your car with an alternator except for the fact that we are generating less energy than we would be if we were utilizing an alternator, and that the energy isn’t being used to recharge the battery itself as it would with an alternator. Harley-Davidson currently dominates motorcycle market share and with much of the interest centered on motocross bikes from Yamaha, Honda, and Kawasaki while Polaris tops UTV sales. Knowing which parts you need and the best Powersports parts to buy is essential to your success in Powersports repairs and maintenance. Whether you need new ATV parts, Motorcycle parts, Scooter parts, or Watercraft parts, or OEM Yamaha, Honda, Polaris, Suzuki, and Kawasaki Powersports parts you can find everything you need here.


  • Motorcycle

  • Why Does A Motorcycle Cannot Run Off A Battery Alone?

      If it does,
    • It would drain the battery very quickly and you would be stuck with recharging your battery frequently and would likely be stranded in the middle of nowhere with a dead motorcycle.
    • The mechanism of the stator is what keeps the battery functioning.

    Why Do Motorcycles Have A Different Types Of Alternators?

    • The alternator system in a motorcycle, or the stator, is different from what other vehicles use.
    • An alternator from a car is bulky and takes up a bit of room
    • Motorcycles are less complex than cars and therefore require less complex parts.
    • That’s why a motorcycle uses the system of a stator instead of a whole regular alternator.
    • There simply isn’t the room to fit a large part like that on a motorcycle.

    The Similarities And Differences Between A Motorcycle Starter And Other Alternators:

    Even though a motorcycle stator and other vehicle alternators, such as an alternator from a car, basically do the same thing, the difference is, that alternators found in other vehicles usually have everything put together in one single part whereas a motorcycle stator and it’s accompanying parts are somewhat dispersed throughout the bike. A battery cannot function without a motorcycle stator and a stator cannot function without the motorcycle battery. Though the function of the battery is brief, it’s also very important. The battery is what gets the motorcycle started in the first place.

  • Industrial

  • Industrial Starters And Alternator:

    Modern vehicle alternators and starters are made from lighter materials, sized for small batteries and minimal electrical loads. They will not sustain high loads without external airflow for cooling. Motor starters are one of the major inventions for motor control applications. A starter is an electrical device which controls the electrical power for starting a motor.Today, motor starters are used on a large scale due to their list of beneficial features. Industrial alternator applications require continuous-duty, high-output alternators built to last while operating safely. One of the primary uses of alternators is in the production of bulk ac power for commercial purposes. In thermal power plants, in hydro power plants, even in nuclear power plants, alternators only convert mechanical energy to electrical energy for supplying to the power system.

    Motor Starter Varieties

    Four particular varieties of motor starters are:
    • Across-The-Line,
    • The Reversing Starter,
    • The Multispeed Starter,
    • Reduced Voltage Starter.

  • Marine

  • For” Excellence At Sea”, Power Your Watercraft With A Marine-Grade Alternator.

    • The choice to upgrade your vessel’s charging system will often include considerations regarding your engine’s alternator.
    • A marine alternator is designed to withstand the rigors of the maritime environment- a special kind of alternator that's designed to handle damp and humid conditions.
    • They come with plated fans, pulleys, and hardware for corrosion resistance and even flame arrestor screens to meet Marine certification.
    • These devices can be installed directly on the main engine or on a generator set.

    How To Choose?

    • Alternators are extremely useful when a vessel carries equipment with high power demands such as thrusters, windlass, and air conditioning.
    • Determine electrical needs over 24 hours, both for charging and direct use, to calculate power requirements. Some supplementary power alternators are compatible only with specific engine makes and models. Be sure to supply this information to the manufacturer.

    What To Look For In Marine-Grade Alternator?

    • Safety: It should meet U.S. Coast Guard Title 33 safety protection standards. If the alternator is being installed on a gasoline engine, the alternator should also comply with international SAE standards for ignition protection.
    • Heavy-duty construction: As Marine alternators operate at sustained high output for much of their lives they require high-temperature grease, large cooling passages, large or multiple fans, heavy-duty bearings, and high-amperage diodes

    Why Do Standard Automotive-Type Alternators Not Used In Marine Charging Systems?

    • Standard automotive-type alternators rarely offer the construction required to meet the demands of large marine charging systems.
    • On most stock marine engines, the factory-supplied alternators are inadequate for charging a large heavily depleted house bank of batteries. In almost all cases they are simply not designed for extended heavy-duty operation charging large banks of batteries.
    • Dual alternators are an increasingly popular alternative on many engines. If excited by a single multi-stage regulator, both alternators can work together to handle large single battery banks.
    • A step-down/step-up alternator may be used along with a standard model to serve as a supplementary power source.

    Steyr Motors, Balmer, WEG Automation, ENAG, Mastervolts, Dynawatt, Volvo Penta are some of the trusted International brands that offer alternators from small boats to cruise ships and for Trawlers to Fishing fleets.

  • I test fitted the starter and noticed that the pinion does not retract when it is released on the engine stand.

  • It is normal for a gear reduction starter to hang in the ring gear when the engine is cranked, and yet does not start. Direct drive starters do not do this because they can rotate the small amount necessary to retract the pinion. Gear reduction starters do not retract in this situation because of the resistance of the gears. The tiny amount of rotation necessary to retract the pinion is amplified because of the gear ratio inside the starter, requiring four to five times the pressure to rotate the gear. All of this gear movement results in the pinion remaining in the ring gear until the engine fires. When the flywheel starts spinning faster than the starter gear, it will "throw" the drive back out.


  • What do I do with the wire that went to the "R" terminal on the original starter?

  • In early original wiring harnesses, the "R" circuit was a ballast resistor bypass. This terminal has no current when the starter is at rest and is +12VDC while cranking. This circuit provided +12VDC to the ignition coil during cranking for easier engine starting. Cars that do not have a ballast resistor (i.e. HEI, MSD, or other aftermarket ignition systems) should not need this connection. In most cases, this wire can be eliminated. If the engine has no ignition during cranking, then the wiring of the coil is going to require an "R" terminal signal. To accomplish this, connect a 3A/400PIV diode in line with the MOTOR SIDE of the solenoid. (Note: This is the terminal on the solenoid which has the cable with the boot from inside the starter motor connected to it. It is opposite the BATTERY terminal on the solenoid. The cathode or banded end of the diode goes away from the starter. This allows current to go from the starter to the coil and yet not from the coil to the starter.)


  • Why does my starter make a whining or grinding noise?

  • This could mean that your starter needs shimming. There are different methods of shimming a starter, depending on which direction the starter needs to be adjusted. If the starter to ring gear tolerance is too tight, you will need to shim the starter away from the ring gear. If the tolerance is loose, your ring gear may be worn or defective. Don't rule this out as a possible cause. You should have 0.020" clearance between the valley of the teeth of the flywheel and the tip of the tooth of the starter drive gear. This can be measured by using white-out, crayon, or feeler gauge with the drive engaged into the flywheel.


  • Why won't my starter crank when it's hot?

  • This is common with full-size starters. Excessive heat against the starter solenoid builds resistance in the coil. There are a few solutions to this problem. (1) You can install a starter relay (see a question - Add a relay) if you do not have one already. (2) Install a heat shield on the solenoid. (3) Replace your full-size starter with a gear reduction starter. The smaller body and variable clocking provide of most mini starters provide more clearance between the exhaust and the starter solenoid.


  • Why do I keep cracking noses on my full-size starters?

  • Refer to the paragraph in this section, whining and grinding noise. These can all be factors. If you are not installing the starter with original equipment bolts, with knurling, the starter will become loose causing misalignment. Backfire while starting causes backlash which creates a sudden excessive impact on the aluminum casting. If your engine is not tuned properly do not continue to crank your engine until your timing is set. The Hitachi and Denso style gear reduction starters have a solid mounting block and pinion that will withstand backfire better than the full-size starter. Full size, direct drive, starters are not recommended for high compression engines.


  • What is the benefit of a high torque starter?

  • High torques starters can provide a number of benefits compared to the factory style direct drive starters. These benefits include:
    • A physically smaller starter which is beneficial when space is an issue due to headers, deep sump oil pans, steering linkage, etc.
    • Many units are rotatable or have solenoids that will sit further away from heat sources.
    • The mini high torque units typically draw about half the amperage of stock starters.
    • They have gear reduction which provides better cranking because they develop higher torque. This is necessary with higher compression engines.

  • Should I use a heat shield?

  • It is not necessary, but it is not a bad idea.


  • Why does my starter seem to "run on" after the switch is released?

  • This is a common complaint on Ford permanent magnet starters, although it can occur on any permanent magnet starter in the right conditions. This situation develops when the ignition terminal on the starter is "jumped" to the battery terminal on the starter and a remote solenoid is used. Permanent magnet starters can actually produce power if they are driven from an outside source (i.e. the starter will act as an alternator once the engine fires and starts spinning). The current produced in the starter for this second or so will flow from the starter's battery terminal to the starter's ignition terminal and hold the solenoid in. This will cause the one to two-second delay in the solenoid release and make an irritating noise. The solution is to wire the starter just like the diagram in our adding a relay question. This will ensure that the ignition switch terminal goes dead the instant the key is released.


  • How can I add a relay for my GM vehicle?

  • By following the schematic below, you can easily add a Ford style relay to your vehicle. Adding a relay that is wired this way will allow more current (amperage) to be provided to the starter solenoid. The higher amperage will produce a better reaction in the solenoid and better engagement for the contacts. Charging Systems FAQ Image
