ENGINE DC CONTROL SYSTEM

CIRCUIT CONDITION – CRANKING:

When the START-STOP SWITCH (SW1) or REMOTE PANEL START SWITCH is momentarily held in the “START” position and then released, Wire 17 from the Printed Circuit Board (PCB ) is connected to frame Ground. PCB action will then deliver battery voltage to a STARTER CONTACTOR RELAY (SCR) via Wire 56, and to an auto- matic CHOKE SOLENOID (CS) via Wire 14.

When battery voltage energizes the STARTER CONTACTOR RELAY (SCR), it’s contacts close and battery output is delivered to the STARTER CONTACTOR (SC) via Wire 16. When the STARTER CONTACTOR (SC) energizes, it’s contacts close, and battery out- put is delivered to the STARTER MOTOR (SM) via Wire 16. The STARTER MOTOR energizes and the engine cranks.

When the STARTER CONTACTOR RELAY (SCR) closes, battery voltage is also delivered to PCB Pin 13 . This voltage is reduced for use as field boost and is output from PCB Pin 13 to the rotor. While cranking, the CHOKE SOLENOID (CS) is energized by grounding Wire 90 cyclically by PCB action (two seconds on, two seconds off).

Also while cranking, PCB action energizes Pin 5, and delivers battery voltage to the Wire 14 circuit. This energizes the FUEL PUMP (FP) via a Red wire, FUEL SOLENOID (FS) via Wire 241 and CHOKE HEATER (CH) via Wire 14. Battery voltage is also delivered to an optional light or hour meter in the Remote Panel, if equipped.

PCB action now holds open Wire 18A to common ground, and the Magneto will induce a spark during cranking.
