TEST 3.5
Disconnect the batteries and remove wires from the B-,
F1, and F2 terminals on the controller.
Using the diode test function on your meter, connect the
positive lead to the B- terminal on the controller.
Connect the negative lead to the F1 terminal on the
controller.
The test should show the presence of a diode
(approx 0.5v).
If the test is good, then skip ahead to test #3.6.
If the test is open or shorted then one or both
directional FET’s are shorted and the controller
must be replaced.
TEST 3.6
Disconnect the batteries and remove wires from the B-, F1, and F2 terminals on the controller.
Using the diode test function on your meter, connect the positive lead to the B- terminal on the

Connect the negative lead to the F2 terminal on the controller.
The test should show the presence of a diode (approx 0.5v). If the test is open or shorted
then one or both directional FET’s are shorted and the controller must be replaced.
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.
