ELECTRICAL SYSTEM TROUBLESHOOTING: IQ
PLUS ELECTRIC VEHICLES
Figure 12-14 Test 13: Speed Sensor Green Wire
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.
See following NOTE.
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 14 – A1 and A2 Motor Voltage
See General Warnings on page 1-1.
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 crossmember between the spring mount and side stringer, just forward of each rear wheel. See
WARNING "Lift only one end..." in General Warnings on page 1-1. 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
(1) motor terminal (white wire) and connect the red (+) probe to the A1 (2) motor terminal (green wire) (Figure
12-15, Page 12-32).
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.
4. As the accelerator pedal is pressed, the voltage reading should increase from approximately 5 volts RMS when
the MCOR limit switch closes, to approximately 32 to 37 volts RMS with the accelerator pedal fully pressed.
See following NOTE.
