Electrical Schematic for a Car
When the driver gets behind that wheel and turns the ignition key to start the engine, the battery is engaged to start the cranking of the engine it also provides power to the rest of the electrical components that will be on during the cranking process. Once the car starts, the battery is disengaged and the car now runs of the electrical supply that is powered by the alternator.
The car's E.F.I. has a diagnostic feature that turns on the battery warning light on the dash when there are any issues associated with the alternator and charging system.
Battery Warning Light
The alternator plays a critical role in the charging and electrical system, within the alternator are several serviceable components that need to be replaced over a period of time, The most common parts that require servicing are:
- Roller Bearings ( Front and Rear ) - Carries the load of the Rotor, when going bad, the Alternator starts to sound very noisy and the area around the bearing become a lot dirtier than normal
- Rectifier - This component monitors and controls the process to charge the battery, it also ensures that power loads in the vehicle have sufficient energy to function. When this component start to go bad the Battery Check Light comes ON.
- Regulator - This component is used to convert current from Alternating Current (AC) to Direct Current (DC) during the charging process
