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

•
Tow/Run switch for proper operation.

See General Warning 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 battery cables as instructed.
See WARNING “To avoid unintentionally starting...” in
General Warning on page 1-1.
