TEST 2.3:
Test the continuity from the motor A1 terminal to the
frame on the motor and from F1 to A1 for open circuits.
Any reading other than an open circuit indicate a
short in the motor. If there is a short in the motor,
stop here and repair or replace the motor.
After any repairs are made, completely retest the vehicle before
lowering the drive wheels to the ground. Failure to retest the vehicle
could result in unexpected movement of the vehicle resulting in injury
or property damage.
This troubleshooting guide is written in sequential order. All tests
must be performed in the order that they are written. Starting in the
middle or skipping sections when not instructed to do so may lead to
invalid test results.
TEST 2.4:
Reaching this point indicates an open circuit in the motor wiring. Check the continuity of all
wires from the controller to the motor.
Repair any open wires then test drive the vehicle.
Stop trouble shooting here and repair the problem. When the repair is completed, completely
retest the vehicle before lowering the drive wheels to the ground.
