Test Procedures
5. Check voltage at the light green wire:
5.1. Set a multimeter to 20 volts DC. Place the black (–) probe on the battery no. 8 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 5.00 volts.
5.2. If the voltage is zero volts, check the continuity of the light green wire from the 24-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. 8 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.
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.
