If the light comes on then the motor
armature windings are open and the
motor must be repaired or replaced. Stop
trouble shooting here and repair the
problem. When the repair is completed,
completely test the vehicle before
lowering the drive wheels to the ground.
1. Make sure the key-switch is in the "OFF" position, then remove
the key.
2. Place the forward-reverse switch in the center "OFF" position.
3. Set the park brake.
4. Place blocks under the front wheels to prevent vehicle movement.
The rear drive wheels may rotate during some of the following tests.
Block the front wheels, raise the rear drive wheels off the ground,
and support the vehicle with jack stands. Failure to do so may cause
the vehicle to move and cause severe bodily injury and/or property
damage.
Rotating rear drive wheels are a potential hazard. Keep hands, arms,
legs and loose clothing away from the rear drive wheels while
conducting tests. Failure to do so may cause serious bodily injury.
