Starters, Alternators and Batteries
The electrical system consists of the battery, starter and alternator. The battery provides power to the starter and, the alternator gives that battery the energy it needs to power the car. If one of these parts is not working properly, the car won’t start or run correctly. We must address any electrical problem before it starts - to avoid being left stranded on the road with a stalled vehicle.
Battery -
Until the vehicle starts, it is the battery that is providing the car’s entire electrical current. This includes the current to the ignition and fuel systems which are responsible for creating the combustion necessary for the engine to run.s.
Starter -
While the battery supplies the power to start the vehicle, the starter is really what gets the engine going. The battery supplies a small amount of power to the starter motor. The starter then rotates the flywheel, which turns the crankshaft and begins the movement of the engine’s pistons. This intricate process is why it is key to make sure the starter works. It is difficult to determine when a starter will fail exactly, but a system check can help recognize the warning signs. An excessive current draw will indicate a worn starter, while a low current draw points to corroded cables or wire connections.
Alternator -
While the engine is running, the alternator will keep the battery charged and the electrical system going. The car can start with a faulty alternator, but it won’t be able to run for an extended period of time. If the alternator is faulty, the vehicle’s electrical system will also perform erratically. Its battery will discharge, and eventually the engine will lose power. A complete system check can tell whether the alternator is generating the proper amount of current and voltage. That way, we have a heads-up before the alternator fails.
"See It in Action"
If you turn the key, the vehicle’s electrical system will go into action. The battery will provide juice to the starter, the starter will turn, and the alternator will give the battery the energy it needs to power the car's lights, defroster, wipers and accessorie
