WIRING SYSTEM 8DÐ67
Start and Charging
General Description
The system consists of the starter switch, starter, AC
generator, starter relay, mode SW (A/T), charge
relay (Diesel) and heater & A/C relay.
When the starter SW is set to the ÒSTÓ position with
the A/T select at "P" (Parking) or "N" (Neutral)
position (Mode SW "ON"), the battery voltage is
applied to the starter solenoid coil through the
starter relay to start the starter. At the same time,
the starter relay (charge relay; Diesel) cuts off the
blower motor and the A/C circuit.
