Neutral start switch to wiring harness plug terminal 7 (YEL-RED).
Wiring harness plug to starter  solenoid (small terminal) (YEL-RED). Also ensure that
black (small terminal) wire is grounded.
Starter solenoid is now “closed,” completing circuit between large terminal (RED-PUR)
and other large terminal (YEL-RED), causing starter motor to crank.
CAUTION
The starter motor is designed to operate under great overload and produce a high
horsepower for its size. It can do this only for a short time, since considerable heat
accumulates and can cause serious damage. For this reason, the cranking motor
must never be used for more than 30 seconds at any one time. Cranking should not
be repeated without a pause of at least 2 minutes to permit the heat to escape.
