SYMPTOMS:

If your vehicle exhibits any of the following symptoms then skip the main troubleshooting
sequence and proceed to 

Symptom Troubleshooting

 later in this section.

• Runs slow in both directions plus high armature and field current in both directions. NOTE:

Armature and field current should be equal.

•

Runs slow in both directions plus high armature current in both directions. NOTE: Field
current will be very low.

•

Runs normal in one direction only plus runs slow or lacks power in the opposite direction
with high armature current in the opposite direction or;

•

Accelerates slowly and exceeds normal speed in the opposite direction with high armature
current only. NOTE: Field current will be very low in the opposite direction.

•

Accelerates slowly and exceeds normal speed in both directions plus high armature current.
NOTE: Field current will be very low.

•

Full speed only.

• Does not run in either direction plus there is noise from motor (hum or whine) with high

field current and low armature current.

•

Jumps into high speed when direction is selected after depressing the accelerator pedal.
Excessive spark when connecting battery

•

Does not run or runs very slow with low motor current and high battery current.

•

Jumps into high speed when direction is selected after depressing the accelerator pedal.

If your vehicle does not exhibits any of the above symptoms then continue with the main
troubleshooting sequence on the following pages.
