ELECTRICAL SYSTEM AND TESTING:
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.
4.
Set a multimeter to 200 volts DC. Insert the red (+) probe of the multimeter into pin 2 (light blue wire) of the 24-pin
connector.
See following CAUTION.
Using an alligator clip, connect the black (–) probe to the B– terminal
of the speed controller
CAUTION
• Do not fully insert probes into the 24-pin plug. Doing so can result in a poor connection.
5.
Place the Tow/Run switch in the TOW position and connect the battery cables, positive (+) cable first.
Connecting the Batteries – Electric Vehicles, Section 1, Page 1-4.
6.
Place the Tow/Run switch in the RUN position.
7.
The multimeter should indicate zero volts DC at this time.
8.
While monitoring the multimeter, plug the battery charger into the vehicle charger receptacle.
9.
After a short delay, the onboard computer should power-up (come out of sleep mode), charger relay should click,
and the ammeter on the charger should indicate that the vehicle batteries are being charged.
10. The multimeter should indicate zero volts DC while the charger is connected to the vehicle.
11. While observing the multimeter, disconnect the DC plug from the vehicle charger receptacle.
12. The multimeter should indicate full battery voltage when the charger is not connected to the vehicle.
13. If any other reading is obtained, check the following items:
– Continuity of the wires in the wire harness
– Onboard computer for proper operation.
See Onboard Computer Gray Wire and Fuse on page 22-29.
– Tow/Run switch for proper operation.
See Tow/Run Switch on page 22-16.
