•
Continuity of the wires in the wire harness
•
Tow/Run switch for proper operation.
See Test Procedure 6 – Tow/Run Switch on page 11-21.
7. If items in step 6 test out okay, the diode has failed open and should be removed from the harness.
Pin 9 Diode Removal, Section 13, Page 13-16.
Test Procedure 9G – Pin 10
See General Warning, Section 10, Page 10-1.
Pin 10 in the 16-pin connector provides a connection point for the key switch to the speed controller. The key
switch provides a +48 volt signal to the speed controller through pin 10 when the key switch is in the ON posi-
tion.
1. Disconnect the batteries and discharge the controller.
See Disconnecting The Batteries on page 10-3.
2. Place chocks at the front wheels and lift the rear of the vehicle with a chain hoist or floor jack. Position
jack stands under the frame crossmember between the spring mount and side stringer, just forward of
each rear wheel.
See WARNING “Lift only one end...” in General Warning, Section 10, Page 10-2.
3. Disconnect the 16-pin connector at the speed controller.
4. With a multimeter set for 200 volts DC, insert the red (+) probe of the multimeter into pin 10 (tan wire) of
the 16-pin connector.
See following CAUTION.
With an alligator clip, connect the black (–) probe to the
B– terminal of the speed controller
CAUTION
• Do not fully insert probes into the 16-pin plug. Doing so can result in a poor connection.
5. Place the Tow/Run switch in the TOW position and connect the battery cables, positive (+) cable first.
Tighten battery terminals to 110 in-lb (12.4 N·m).
6. With the Tow/Run switch in the TOW position, the multimeter should indicate zero volts.
7. Place the Tow/Run switch in the RUN position and the key switch in the ON position.
8. With the key switch in the ON position, the multimeter should indicate full battery voltage (approximately
48 volts). With the key switch in the OFF position, the reading should be zero volts.
9. If any other reading is obtained, check the following items:
•
Continuity of the wires in the wire harness
