CIRCUIT CONDITION-RUNNING:
With the FUEL PUMP (FP) and FUEL SOLENOID (FS)
operating and ignition occurring, the engine should
start, and the START-STOP SWITCH (SW1) is
released.
A voltage is induced into the Stator's BATTERY
CHARGE WINDING. This voltage is delivered to the
ENGINE CONTROLLER BOARD (PCB) via Wire 66 to
prevent STARTER MOTOR engagement above a cer-
tain rpm.
Circuit board action terminates DC output to the
STARTER CONTACTOR RELAY (SCR), which then
de-energizes to end cranking. Circuit board action ter-
minates DC output to the CHOKE SOLENOID (CS).
The choke will go to a position determined by the
CHOKE HEATER (CH).
The LOW OIL PRESSURE SWITCH (LOP) is nor-
mally closed. After start-up, engine oil pressure
will open the LOP.
