Test Procedures
4.
With a multimeter set for 200 volts DC, insert the red (+) probe of the multimeter into pin 1 (tan wire) of the 24-pin
connector. See following CAUTION. With an alligator clip, connect the black (–) probe to the B– terminal
of the speed controller (Figure 12-20, Page 12-40).
CAUTION
• Do not fully insert probes into the 24-pin plug. Doing so can result in a poor connection.

5.
Place the Run/Tow switch in the TOW position and connect the battery cables, positive (+) cable first. See
Connecting the Batteries – Electric Vehicles, Section 1, Page 1-4.
6.
With the Run/Tow switch in the TOW position, the multimeter should indicate zero volts.
7.
Place the Run/Tow switch in the RUN position and the key switch in the ON position.
8.
With the key switch in the ON position, the multimeter should indicate full battery voltage (approximately 48 volts).
With the key switch in the OFF position, the reading should be zero volts.
9.
If any other reading is obtained, check the following items:
– Continuity of the wires in the wire harness
– Run/Tow switch for proper operation. See Run/Tow Switch on page 12-18.
– Key switch for proper operation. See Key Switch and MCOR Limit Switch Circuit on page 12-23.
Pin 17
See General Warnings on page 1-1.
Pin 17 in the 24-pin connector provides a connection point for the solenoid coil to the speed controller. The speed
controller activates the solenoid coil by providing a ground to the solenoid coil at the appropriate time.
1.
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.
