POWERDRIVE CHARGER Test Procedures

6. Reconnect the three-pin connector at the motor speed sensor. Using a multimeter set to 20 volts DC, place the
black (–) probe on the battery no. 6 (6 x 8-Volt battery set) negative post and place the red (+) probe (with
insulation-piercing probe) on the green wire between the three-pin connector and the motor speed sensor.
6.1. Raise one rear wheel off ground. Slowly turn the rear wheel to rotate the motor armature. As the armature
rotates, the voltage reading should alternate from zero to approximately 4.85 volts. The voltage reading will
fluctuate from zero to 4.85 volts and back to zero four times for each revolution of the motor armature.
NOTE: The voltage reading of 4.85 is an approximate reading. The actual reading may vary from 4.50 to 5.00 volts.
6.2. Replace the speed sensor if:
– There is no voltage reading.
– The voltage reading is not above 3.50.
– The voltage reading does not fluctuate as the motor is turned.
TEST PROCEDURE 22 – Solenoid Continuity
See General Warnings on page 1-2.
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 rails just forward of each spring mount.
See WARNING “Lift only one end...” in
General Warnings on page 1-2.
2. Disconnect the batteries and discharge the controller. See Disconnecting the Batteries – Electric Vehicles
on page 1-4.
3. Disconnect the two wires that are crimped together from the forward large post of the solenoid.
4. Using a multimeter set to 200k ohms, place the black (–) probe on one solenoid large post and place the red
(+) probe on the other large post. The reading should be no continuity.
5. Connect the three wires crimped together to the forward large solenoid post. Install washer and nut on large
solenoid post and tighten to 77 in·lb (8.7 N·m).
6. 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.
7. 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 solenoid should click and the
multimeter should indicate continuity. If the reading is no continuity, replace the solenoid.
TEST PROCEDURE 23 – Forward/Reverse Rocker Switch
See General Warnings on page 1-2.
Forward/Reverse Rocker Switch Test with the IQDM Handset
1. Turn the key switch to the OFF position and place the Forward/Reverse switch in the NEUTRAL position.
2. Connect the IQDM to the vehicle.
3. Test FORWARD INPUT.
3.1. Access the Test menu and select FORWARD INPUT by using the SCROLL DISPLAY buttons. The IQDM
should indicate OFF when the Forward/Reverse switch is in the NEUTRAL or REVERSE position.
