Test Procedure 10D – Pin 19
See General Warning, Section 10, Page 10-1.
Pin 19 in the 24-pin connector provides a connection point for the reverse buzzer to the speed controller.
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 10-1.
3. Disconnect the 24-pin connector at the speed controller.
4. Place a jumper wire with an alligator clip between the B– terminal of the speed controller (use alligator
clip for this connection) and pin 19 (orange/white wire) of the 24-pin connector (Figure 11-21,
Page 11-32) . See following CAUTION.
CAUTION
• Do not fully insert probes into the 24-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. Place the Tow/Run switch in the RUN position.
7. The reverse buzzer should sound when the Tow/Run switch is in the RUN position.
8. If any other activity is observed, check the following items:
• Continuity of the wires in the wire harness
• Reverse buzzer for proper operation. See Test Procedure 17 – Reverse Buzzer on page 11-42.
• Tow/Run switch for proper operation. See Test Procedure 6 – Tow/Run Switch on page 11-21.
