Refer to the troubleshooting chart (Table 8) for suggestions about possible
causes of the various faults.
SPEED LIMIT POT FAULT
The controller will not display a fault if there is a problem with the speed limit pot
or its wiring. However, if the speed limit pot is broken or if any of its wires is open,
the vehicle drive speed will be limited to the specified minimum speed in the
selected mode. Open circuit faults can be verified by observing the speed limit pot
display in the Test Menu of the handheld programmer as this pot is adjusted. If
the speed limit pot display does not change as the pot is adjusted, there is a problem
with the pot wiring or the pot itself.
