Controller
The Workman controller is secured to the rear frame un-
der the controller cover beneath the bed (Fig. 41). The
controller uses inputs from several vehicle switches (on/
off, forward/reverse, accelerator pedal, supervisor,
charger interlock, motor temperature, accelerator po-
tentiometer) to accurately control vehicle speed, vehicle
direction (forward and reverse) and regenerative brak-
ing. An internal thermal sensor prevents overheating of
the controller.
NOTE: If the controller LED and vehicle status light are
flashing, attempt to reset the controller by turning the
On/Off switch to OFF, waiting a few seconds and then
turning the switch to ON. If LED and status light continue
flashing, proceed with fault code identification and nec-
essary action.

harness ground.
Terminal B+: Positive (+) cable from main contac-
tor post and wire harness fusible link (FL3).
Terminal M1: Cable to traction motor armature A2
post.

Terminal M2: Cable to traction motor armature A1
post.
Terminal F1: Cable to traction motor field F1 post.
Terminal F2: Cable to traction motor field F2 post.

If wire harness connector is removed from controller,
both harness connector and controller socket should be
filled with dielectric gel to prevent corrosion of connec-
tion terminals and potential controller damage. Apply
gel fully to both harness connector and controller sock-
et, plug harness connector into controller to distribute
gel, unplug harness connector, reapply gel to both sur-
faces and plug harness connector into controller.

A LED exists on the controller to identify normal opera-
tion or faults that will prevent the vehicle from operating
correctly. The vehicle status light on the dash panel dis-
plays the same information as the LED on the controller.
See chart below for light pattern fault codes identified by
the controller LED and vehicle status light.
