Charging System: Notes

The charging system consists of the following components:

• Generator
• Charging system warning indicator
• Necessary wiring and cables

The charging system is a negative ground system. The generator (including an internal voltage regulator) is belt-driven by the engine accessory drive system. When the engine is started, the generator begins to generate AC, which is internally converted to DC. This current is then supplied to the vehicle electrical system through the output (B+) terminal of the generator.

Vehicles equipped with a 4.6L (3V) have a one way clutch (OWC) in the generator pulley. The OWC pulley temporarily disengages the generator rotor from the front end accessory drive (FEAD) system during high deceleration rates on the engine. This may decrease noise, vibration and harshness (NVH) (belt chirp) and may increase belt life. The OWC pulley and generator/regulator must be installed as an assembly.
