TEST PROCEDURE 10 – Pins 1, 2, and 3
See General Warnings on page 1-1.
Pins 1, 2, and 3 in the 16-pin connector provide a connection point from the MCOR potentiometer to the speed
controller.
1. Disconnect the battery cables and discharge the controller as instructed. See WARNINGS "To avoid
unintentionally starting..." and "After disconnecting the batteries, wait 90 seconds..." in General
Warnings on 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. See WARNING "Lift only one end..." in
General Warnings on page 1-1.
3. Disconnect the 16-pin connector at the speed controller.
4. Using a multimeter set for 20k ohms, insert the red (+) probe of the multimeter into pin 2 (yellow wire) of the
16-pin connector. See following CAUTION. Insert the black (–) probe into pin 3 (purple/white wire) of the 16-pin
connector (Figure 12-11, Page 12-24).
CAUTION
• Do not fully insert probes into the 16-pin plug. Doing so can result in a poor connection.
5. With the accelerator pedal fully up (not pressed), the multimeter should read approximately 1k ohms.
6. Slowly press the accelerator pedal while monitoring the multimeter. The resistance should rise as the pedal is
pressed. When the pedal is all the way to the floor, the multimeter should indicate between 5.67k ohms and
7.43k ohms.
