Test Procedures
– Tow/Run switch for proper operation. See Test Procedure 6 – Tow/Run Switch on page 12-19.
TEST PROCEDURE 12 – Pin 6
See General Warnings on page 1-1.
Pin 6 in the 16-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
on page 1-3.
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.
200 DCV Setting (reading with OBC powered-up and accelerator pedal pressed)

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 12-16, 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 batteries. See Connecting the Batteries –
Electric Vehicles on page 1-3.
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.
