Curtis PMC Troubleshooting
Page 21
Connect a volt meter across the PMC B+ and PMC
M- terminals.
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 not be equal to
the battery voltage.
•
If you have full battery voltage then the
PMC control is shorted and must be
replaced. Stop trouble shooting here and
repair the problem. When the repair is
completed, completely retest the vehicle
before lowering the drive wheels to the
ground, otherwise continue with the next
test.
If the voltage at pin #2 is correct and the voltage at ‘M-’ is correct, then there is a short in the
harness between the wire connected to the PMC ‘M-’ and main battery negative. Stop trouble
shooting here and repair the problem. When the repair is completed, completely retest the
vehicle before lowering the drive wheels to the ground.
STOP
Stop, do not continue. If you reached this point without a solution, then you may have an
unanticipated problem or have made an error during testing. It is important to review the
trouble shooting steps that have led to this point. The tests may need to be repeated.
