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 23 – Forward/Reverse Rocker Switch
on page 12-35.
– Tow/Run switch for proper operation. See Test Procedure 6 – Tow/Run Switch on page 12-19.

TEST PROCEDURE 15 – Pin 9
See General Warnings on page 1-1.
Pin 9 in the 16-pin connector provides a connection point for the Tow/Run switch to the speed controller. The switch
provides a +48 volt signal to the speed controller through pin 9 when the Tow/Run switch is in the RUN position.
1. Disconnect the batteries and discharge the controller. See Disconnecting the Batteries – Electric Vehicles
on page 1-3.
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 rails just forward of each spring mount. See WARNING "Lift only one end..." in
General Warnings on page 1-1.
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 9 (gray 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 12-19, Page 12-30).
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 batteries. See Connecting the Batteries –
Electric Vehicles on page 1-3.
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.
