Charging System: Description and Operation
When the
Ignition Switch (X134) is in position II, battery voltage is applied to the
charging system fault light. When the Generator (Z106) is being turned by the engine, its stator windings are excited by voltage applied to the Generator via the charging system fault light. The Generator begins to produce electricity in order to charge the vehicle Battery (P104). If the Generator fails to produce power, the Generator grounds the fault light control wire, causing the charging system fault light to glow.
