11. Attach the positive lead of the voltmeter to the "hold
coil terminal" of the solenoid. Attach the negative
lead of the voltmeter to the "common ground termi-
nal" of the solenoid. Turn the ignition switch to the
"RUN" position. The voltmeter should read a mini-
mum of 9 volts. Less than 9 voltsindicates a bad cir-
cuit. Also, there should be a 0.87 amp current draw.
12. Attach the positive lead of the voltmeter to the "pull
coil terminal" of the solenoid. Attach the negative
lead of the voltmeter to the "common ground termi-
nal" of the solenoid.
Turn the key switch to the "RUN" position. A volt-
age of at least 9 volts should be present for approxi-
mately two seconds, and the solenoid plunger should
retract. Also there should be a 60.3 amp draw.
13. Attach the voltmeter leads between the solenoid
"common ground" terminal and a good ground on
the frame. While the solenoid is in the "PULL" and
"HOLD" positions, the voltmeter should read 0 volts.
If there is voltage, the ground circuit needs to be
checked.
