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 Fault Code 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 Industries 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 Tag and disconnect all power cables from the

circuits could result in death or
serious injury. Remove all rings,
watches and other jewelry.
3 Press the release tab on the motor controller
harness connector and remove the motor
controller harness connector from the motor
controller.
4 Set an ohmmeter to diode test mode.
5 Connect the leads from an ohmmeter to test
each motor controller terminal combination

bias (diode test).
Result: All desired results must be within the
specified range. If any test has a result not
within the specified range, replace the motor
controller.
