TEST PROCEDURE 9 – Solenoid Continuity
See General Warnings on page 1-2.
Solenoid Continuity Test with the IQDM Handset
1.
If necessary, see Testing Basics on page 28-16.
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
3.
Connect the IQDM to the vehicle.
4.
Access the Monitor menu and select MAIN CONT DRIVER by using the SCROLL DISPLAY buttons. The
IQDM should indicate OFF.
5.
Turn the key switch to the ON position and place the Forward/Reverse switch in the FORWARD position.
6.
Press the accelerator pedal. When the controller energizes the solenoid coil, the IQDM should indicate ON. If not,
check the KEY, FORWARD, REVERSE and FOOT INPUTS to the controller.
Also check the 16-pin connector at the speed controller.
See Test Procedure 15 – 16-Pin Connector on
7.
If the IQDM displays readings other than those described above and the wiring is found to be correct, proceed to
the following procedure,
Solenoid Continuity Test without the IQDM Handset
.
Solenoid Continuity Test without the IQDM Handset
1.
If necessary, see Testing Basics on page 28-16.
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
3.
Disconnect the batteries and discharge the controller.
See Disconnecting the Batteries – Electric Vehicles
4.
Disconnect the 6-gauge yellow wire and pre-charge resistor from large post of solenoid.
See following NOTE.
NOTE:
When disconnecting heavy gauge wires from solenoid, use a second wrench on the lower nut of the terminal
post to hold post steady, preventing damage to the solenoid.
If the pre-charge resistor is not disconnected, the meter will read approx. 250 Ohms.
5.
Check for continuity between the two large posts of the solenoid. The reading should be no continuity. If continuity
is found, the solenoid has failed CLOSED and must be replace.
See Solenoid Removal on page 29-13.
6.
Reconnect the 6-gauge yellow wire and pre-charge resistor to the solenoid and secure with washer and nut.
Tighten nut to 77 in·lb (8.7 N·m).
7.
Place the Tow/Run switch in the TOW position and connect the batteries.
See Connecting the Batteries –
Electric Vehicles on page 1-4.
WARNING
• Keep people and equipment clear from rotating rear wheels. Do not allow persons under the car.
Contact with rotating rear wheels could result in serious personal injury.
8.
Change the multimeter to measure resistance.
9.
Place the Tow/Run switch in the RUN position, turn the key switch to the ON position, place the Forward/Reverse
rocker switch in the FORWARD position, and press the accelerator pedal. The rear tire should rotate and
the multimeter should show a change in resistance. If not, replace the solenoid.
