Test Procedures
ELECTRICAL SYSTEM AND TESTING:
ELECTRIC VEHICLES
8.
Place the Forward/Reverse switch in the FORWARD position. The multimeter should indicate full battery voltage
(approximately 48 volts).
9.
Insert the red (+) probe of the multimeter into pin 11 (blue wire) of the 24-pin connector. Leave the black (–) probe
(alligator clip) connected to the B– terminal of the speed controller.
See previous CAUTION.
10. Place the Forward/Reverse switch in the NEUTRAL position. The multimeter should indicate zero volts DC
at this time.
11. While monitoring the multimeter, place the Forward/Reverse switch in the FORWARD position. The multimeter
should still indicate zero volts.
12. Place the Forward/Reverse switch in the REVERSE position. The multimeter should indicate full battery voltage
(approximately 48 volts).
13. If any other reading is obtained, check the following items:
– Continuity of the wires in the wire harness
– Forward/Reverse switch for proper operation.
See Forward/Reverse Rocker Switch on page 22-33.
– Tow/Run switch for proper operation.
See Tow/Run Switch on page 22-16.

Detail A: Front of 24-Pin Connector
Figure 22-16
Test: Pin 10 (Black Wires)
TEST PROCEDURE 16 – Pin 1
See General Warning on page 1-1.
Pin 1 in the 24-pin connector provides a connection point for the key switch to the speed controller. The key switch
provides a +48 volt signal to the speed controller through pin 1 (tan wire) when the key switch is in the ON position.
1.
Disconnect the batteries and discharge the controller.
See Disconnecting the Batteries – Electric Vehicles,
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 Warning on page 1-1.
3.
Disconnect the 24-pin connector at the speed controller.
