PMC CONTROL
Disconnect the wire from the ‘M-’ terminal on the
PMC control and tape it off to prevent electrical
contact. Connect a volt meter across the PMC #2
terminal and battery negative.
Turn the key-switch on, close all interlock
switches (if equipped), depress the
accelerator pedal to engage the first micro
switch only (creep speed), then perform the
following tests:
•
The meter reading should be between 6
and 6.5 volts.
•
If the voltage at pin #2 is not 6 to 6.5 volts,
then go to the
ACCELERATOR
sequence
in the Main Troubleshooting Sequence,
otherwise continue with the next test.
1. Make sure the key-switch is in the “OFF” position, then remove
the key.
2. Place the forward-reverse switch in the center “OFF” position.
3. Set the park brake.
4. Place blocks under the front wheels to prevent vehicle movement.
5. Disconnect the main positive and negative cables at the batteries.
The rear drive wheels may rotate during some of the following tests.
Block the front wheels, raise the rear drive wheels off the ground,
and support the vehicle with jack stands. Failure to do so may cause
the vehicle to move and cause severe bodily injury and/or property
damage.
Rotating rear drive wheels are a potential hazard. Keep hands, arms,
legs and loose clothing away from the rear drive wheels while
conducting tests. Failure to do so may cause serious bodily injury.
