ELECTRICAL SYSTEM AND TESTING
Test Procedure 9E – Pins 8 and 16
See General Warnings, Section 1, Page 1-1.
Pins 8 and 16 in the 16-pin connector provide a connection point for the Forward/Reverse rocker switch to the
speed controller. The switch provides a +48 volt signal to the speed controller through pin 8 when the Forward/
Reverse switch is in the FORWARD position and provides a +48 volt signal on pin 16 when the Forward/
Reverse switch is in the REVERSE position.
1. Disconnect the battery cables as instructed. See WARNING "To avoid unintentionally starting..." in
General Warnings, Section 1, Page 1-1.
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.
3. Disconnect the 16-pin connector at the speed controller.
4. Using a multimeter set for 200 volts DC, insert the red (+) probe of the multimeter into pin 8 (white wire)
of the 16-pin connector. See following CAUTION. Using an alligator clip, connect the black (–) probe to
the B– terminal of the speed controller (Figure 11-15, Page 11-33).
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. Place the Tow/Run switch in the RUN position and the Forward/Reverse switch in the NEUTRAL position.
The multimeter should indicate zero volts DC at this time.
7. While monitoring the multimeter, place the Forward/Reverse switch in the REVERSE position. The mul-
timeter should still indicate zero volts.
8. Place the Forward/Reverse switch in the FORWARD position. The multimeter should indicate full battery
voltage (approximately 48 volts).
9. Insert the red (+) probe of the multimeter into pin 16 (blue wire) of the 16-pin connector. Leave the black
(–) probe (alligator clip) connected to the B– terminal of the speed controller. See previous CAUTION.
10. Place the Forward/Reverse switch in the NEUTRAL position. The multimeter should indicate zero volts
DC at this time.
11. While monitoring the multimeter, place the Forward/Reverse switch in the FORWARD position. The mul-
timeter should still indicate zero volts.
12. Place the Forward/Reverse switch in the REVERSE position. The multimeter should indicate full battery
voltage (approximately 48 volts).
13. If any other reading is obtained, check the following items:
• Continuity of the wires in the wire harness
• Forward/Reverse switch for proper operation. See Test Procedure 15 – Forward/Reverse Rocker
Switch on page 11-40.
