Test Procedures
CAUTION
• Do not fully insert probes into the 24-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.
7. Set a multimeter to 20k ohms. Insert the red (+) probe of the multimeter into pin 15 (yellow wire) at the 24-pin
connector. Connect the black (–) probe into pin 13 (white wire). See previous CAUTION.
8. With the accelerator pedal fully up (not pressed), the multimeter should indicate between 5.67k ohms and
7.43k 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 ohms.
10. If any other reading is observed, check the continuity of the wires in the wire harness.
11. Connect the batteries. See Connecting the Batteries – Electric Vehicles, Section 1, Page 1-4.
Detail A: Front of 24-Pin Connector
Pin 8
See General Warnings on page 1-1.
Pin 8 in the 24-pin connector provides a connection point for the MCOR limit switch to the speed controller.
1. Disconnect the batteries and discharge the controller. See Disconnecting the Batteries – Electric Vehicles,
Section 1, Page 1-4.
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 crossmember between the spring mount and side stringer, just forward of each rear wheel. See
WARNING "Lift only one end..." in General Warnings on page 1-1.
3. Disconnect the 24-pin connector at the speed controller.
4. Place the Tow/Run switch in the TOW position and connect the battery cables, positive (+) cable first. See
Connecting the Batteries – Electric Vehicles, Section 1, Page 1-4.
