ELECTRICAL SYSTEM AND TESTING
Test Procedure 9A – Pins 1, 2, and 3, Continued:
7. Using a multimeter set for 20k Ω (ohms), insert the red (+) probe of the multimeter into pin 2 (yellow wire)
at the 16-pin connector. Connect the black (–) probe into pin 1 (white/black wire). See previous CAU-
TION.
8. With the accelerator pedal fully up (not pressed), the multimeter should indicate between 5.67k Ω (ohms)
and 7.43k Ω (ohms).
9. Slowly press the accelerator pedal while monitoring the multimeter. The resistance should drop as the
pedal is pressed. When the pedal is all the way to the floor, the multimeter should indicate approximately
1k Ω (ohms).
10. If any other reading is observed, check the continuity of the wires in the wire harness.
Test Procedure 9B – Pin 5
See General Warnings, Section 1, Page 1-1.
Pin 5 in the 16-pin connector provides a connection point for the solenoid lockout circuit from the onboard
computer to the speed controller.
1. Disconnect the battery cables as instructed. See WARNING "To avoid unintentionally starting..." in
General Warnings, Section 1, Page 1-1.
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.
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 5 (light blue
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 11-12, Page 11-29).
CAUTION
• Do not fully insert probes into the 16-pin plug. Doing so can result in a poor connection.
