Many car owners believe they need a new starter motor when they have problems cranking their engine. It’s best to have your starter “bench-tested” at your local auto parts store before purchasing a new one. If – at a normal rpm under load – your starter cranks, your problem could be with the other parts that use and produce electricity to keep your engine running: your voltage regulator, battery or alternator.

The voltage regulator on a modern vehicle is connected to its on-board computer system. The voltage regulator adjusts the small field current to create continuous voltage at the stator output. The output current of the alternator is quite a bit more extensive than the field current. In recent years, voltage regulators have been altered to adjust to the battery charging voltage generated by the alternator and the air temperature increased by air flow sensors.

An alternator powers a vehicle’s electrical system and charges its battery when the engine’s ignition is on. A car alternator is much more beneficial than a direct-current generator because it doesn’t use a communicator. Therefore, alternators are stronger, more economical, less heavy and trouble-free than DC generators. A contemporary car alternator usually has a voltage regulator built right in. It’s best to replace faulty alternators with used alternators from a reputable local or online auto parts store.

Other alternator parts may need to be replaced to allow your car’s ignition to fire, too. For instance, you may need to replace your alternator wiring. An online retailer like All Import Auto Parts is an outstanding source for electrical system components. They supply used auto parts, salvage car parts, recycled auto parts and junkyard parts. Online auto parts dealers allow you to search and compare prices to get the best possible deal because they have every kind of import parts for car.
