4. Using a multimeter set for 200 volts DC, insert the red (+) probe of the multimeter into pin 6 (green 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 12-13, Page 12-26).
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, key switch in the ON position, and Forward/Reverse switch in
the FORWARD position.
7. The multimeter should indicate zero volts DC at this time.
8. While monitoring the multimeter, slowly press the accelerator pedal and hold the pedal at approximately 20%
of full travel.
9. After a short delay, the onboard computer should power-up (come out of sleep mode).
10. The multimeter should indicate full battery voltage (approximately 48 volts) when the accelerator pedal is pressed.
11. While observing the multimeter, release the accelerator pedal.
12. The multimeter should indicate zero volts when the accelerator pedal is not pressed.
13. If any other reading is obtained, check the following items:
– Continuity of the wires in the wire harness
– Onboard computer for proper operation. See Test Procedure 19 – Onboard Computer Gray Wire on
page 12-33.
– Tow/Run switch for proper operation. See Test Procedure 6 – Tow/Run Switch on page 12-19.
– Key switch and MCOR limit switch for proper operation. See Test Procedure 8 – Key Switch and MCOR
Limit Switch Circuit on page 12-20.
