Test Procedure 10E – Pins 10 and 11, Continued:
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 11 (blue wire) of the 24-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 16 – Forward/Reverse Rocker
•
Tow/Run switch for proper operation.
See Test Procedure 6 – Tow/Run Switch on page 11-21.
Test Procedure 10F – Pin 1
See General Warning, Section 10, Page 10-1.
Pin 1 in the 24-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 1 (tan wire) when the key switch is in the
ON position.
1. Disconnect the battery cables as instructed.
See WARNING “To avoid unintentionally starting...” in
General Warning, Section 10, Page 10-1.
