GENERAL DESCRIPTION
SYSTEM REPAIR
START AND CHARGING
CHASSIS ELECTRIC L 8-38
The system consists ofthe starter switch, starter, generator, starter relay, clutch start SW (M/T), mode SW (A/T),
heater & AJC relay.
When the starter SW is set to the "ST" position with the AJT select lever at "P" (Parking) or "N" (Neutral)~ osition
(Mode SW "ON"), or the clutch pedal depressed (Clutch start SW "ON"), the battery positive voltage is ~pplied
to the starter solenoid coil through the starter relay to start the starter. At the same time, the starter re ay cuts
off the blower motor and the AJC circuit.
