TROUBLESHOOTING Test Procedures

4.1. With Tow/Run switch in the RUN position and 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 red (+) probe on red wire terminal
socket in three-pin connector. The voltage reading should be approximately 15 to 16 volts.
4.2. If the voltage reading is zero volts, check the continuity of the red wire from the 16-pin connector at the
speed controller to the three-pin connector at the motor speed sensor. If the wire continuity is correct,
replace the speed controller.
4.3. If the reading is below 14 volts, replace the speed controller.
4.4. If the voltage reading is correct, proceed to the following step.
5. Check voltage at the light green wire:
5.1. 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 on the light green wire female terminal in the three-pin connector
at the motor speed sensor. The voltage reading should be from 4.60 to 4.90 volts.
5.2. If the voltage is zero volts, check the continuity of the light green wire from the 16-pin connector at the
speed controller to the three-pin connector at the motor speed sensor. If the continuity is correct, replace
the speed controller.
5.3. If reading is below 3.50 volts, check the continuity of the wires and plug and replace the speed controller if
necessary.
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 any of the following results occur:
– 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 13 – A1 and A2 Motor Voltage
See General Warnings on page 1-2.
NOTE: This is a voltage test.
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. See also following WARNING.
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.
2. With the batteries connected and using a multimeter set to 200 volts DC, place the black (–) probe on the A2
motor terminal (white wire) and connect the red (+) probe to the A1 (green wire) motor terminal.
3. With Tow/Run switch in the RUN position, place the Forward/Reverse switch in the FORWARD position, turn key
switch to the ON position and slowly press accelerator pedal.
