WSG-1068 STARTER SYSTEM
Pinpoint Test B - Starter Does Not Crank
Inspection and Verification
1. Visually inspect for obvious signs of mechanical and electrical damage.
2. Visually inspect for and note auxiliary system connections not shown on the Recommended
Customer Connections Wiring Schematic.
Normal Operation
Terminals 30 and 87A of the starter lockout relay are normally closed while the ignition switch is in the
start/crank position and the engine rpm is less than 600. Battery voltage flows to the starter solenoid
engaging the starter. When the engine has reached 600 rpm or greater the GCP will ground the relay
terminal 85 and open terminals 30 & 87A which will not allow the starter to be engaged while the engine
is operating above 600 rpm. Once the relay is energized it will not reset until the GCP is turned off and
then back on.
