Section 5
ENGINE DC CONTROL SYSTEM
INTROdUCTION
The engine DC control system includes all com-
ponents necessary for the operation of the engine.
Operation includes rest, priming, cranking, starting,
running and shutdown. The system is shown sche-
matically.
OPERATIONAL ANALYSIS
CIRCUIT CONDITION – REST:
Battery voltage is available to the Printed Circuit Board (PCB)
from the vehicle BATTERY via the positive (RED) battery cable
to the isolated positive (RED) terminal stud, located in the control
panel. The power is supplied to Wire 13, a 7.5 amp FUSE (F1),
the STARTER CONTACTOR RELAY (SCR) and Wire 15/Pin 4 on
the PCB. However, PCB action is holding the circuits open, and no
action can occur.
Printed Circuit Board action (only) allows voltage to be supplied
to Wires 17 and 18 for start and stop actions on the START-STOP
SWITCH (SW1) and remote panel connector
.
