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. With the Tow/Run switch in the TOW position, the multimeter should indicate zero volts.
7. Place the Tow/Run 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
– Tow/Run switch for proper operation. See Test Procedure 6 – Tow/Run Switch on page 14-19.
– Key switch for proper operation. See Test Procedure 8 – Key Switch and MCOR Limit Switch Circuit
on page 14-20.
TEST PROCEDURE 17 – Pin 12
See General Warnings on page 1-1.
Pin 12 in the 16-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. 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.
4. Place a jumper wire with an alligator clip between the B– terminal of the speed controller (use alligator clip for this
connection) and pin 12 (blue/white wire) of the 16-pin connector (Figure 14-19, Page 14-32). See following
