Charging System: Description and Operation
OPERATIONWhen engine is stopped
When the ignition switch is switched to the ON position, electricity flows from the generator "L" terminal to the field coil, and at the same time the charging warning light illuminates.
When engine is being started or has started
When the engine is started, charging voltage is applied to the generator "L" terminal, with the result that the charging warning light is extinguished. In addition, because battery positive voltage is applied to the generator "S" terminal, this battery positive voltage is monitored at the IC voltage regulator, thus switching the current to the field coil on and off and thereby controlling the output voltage of the generator. Power is supplied to each load from the generator "B" terminal.
NOTE: The indicator light (Brake warning light, etc.,) functions as a back-up for the flow of electricity to the field coil it there is a disconnection or damaged wiring of the charging warning light.
- This warning light illuminates when the ignition key is in the ON position, and switches off after the engine has started. This warning light illuminates when the drive belt breaks or the trouble occurs in the charging system.
