Study Notes

Alternator Location and Drive

Alternators are positioned on the front lower right side of the engine.
They are driven by a belt connected to the engine crankshaft.

Alternator Function and Current Conversion

Alternators produce alternating current (AC).
Diodes within the alternator convert AC to direct current (DC).
Diodes are solid state devices, prone to damage if current flows in reverse.

Alternator System Control

Each alternator system has an independent ON-OFF switch.
A solid state voltage regulator automatically regulates alternator field current.
When an alternator is switched ON, its positive output is routed through individual shunts to the main tie bus.
