For almost ten years now, Hi Test has been providing the automotive industry with quality alternators. An alternator is one of the three major components that powers up your vehicle (the battery and the voltage regulator are the other two). This part of your engine electrical system works together with the battery to generate power for other electrical components like headlights, wiper blades, and power windows. And because it is also a necessary component of your engine, without the alternator, the car battery cannot produce electricity needed by the spark plugs to burn fuel in order for a car to run. That's why it is necessary to have a top-quality alternator by Hi Test installed in your ride.In detail, the alternator's job is to convert the mechanical energy generated by the engine into electrical energy needed to charge your car's battery. And from the battery, all sorts of car parts, equipments, and devices get their much needed electricity to work including the engine electrical components like distributors, ignition coils and spark plugs.That's why Hi Test has a complete line-up of car alternators that perfectly fit and match plenty of makes and models from cars, trucks, SUVs to other types of vehicles. Although relatively young in the field of car part manufacturing compared to other brands, Hi Test has already created OE-quality alternators tried and tested by top car manufacturers. And because the alternators that Hi Test manufactures are made from only the finest materials of steel, aluminum, and stator and rotor components, Hi Test alternators don't easily heat up, ensuring their long-lasting performance even if exposed to extremely high temperatures under the hood.
