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 posi-
tion. 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
•
Tow/Run switch for proper operation.
See Test Procedure 6 – Tow/Run Switch on page 11-21.
