Motor Controller
The drive motor controller is located under the non-
steer end drive chassis cover. The drive motor
controller can recognize machine drive
malfunctions and display controller fault codes by
flashing a LED at the ground controls and on the
motor controller. See the Troubleshooting section
of this manual for a list of fault codes and
additional information. There are no adjustments
needed on the drive joystick controller. For further
information or assistance, consult the Genie
Service Department.
How to Test the Motor Controller
Note: Use the following procedure to test the motor
controller. If the motor controller is found to be
faulty, note which test failed and which fault code
(if any) was present at the time of failure.
1 Turn the key switch to the off position and
disconnect the battery packs from the machine.
2 Remove the chassis cover from the non-steer
end of the machine.
3 Tag and disconnect all power cables from the
motor controller.
Electrocution/burn hazard. Contact
with electrically charged circuits
could result in death or serious
injury. Remove all rings, watches
and other jewelry.
4 Press the release tab on the motor controller
harness connector and remove the motor
controller harness connector from the motor
controller.
5 Connect the leads from an ohmmeter to test
each motor controller terminal combination
listed below and check for resistance.
Result: All desired results must be 500 kilohms
or more. If any test has a result less than
500 kilohms, replace the motor controller.
