Electrical Troubleshooting
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.
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.
STOP
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.
