Check Procedure 8—Motor speed sensor
Please refer to Chapter 1 “Protection for Electrical Safety”.

NOTE:
• The following operations must be conducted on a flat surface. To prevent injury or property
loss, make sure that the passage of the electric vehicle is unblocked before moving it.
1. Turn the key switch to OFF and turn Forward/Reverse switch to NEUTRAL.
2. Use a multimeter set to 200V DC, connect the black (-) probe to the negetive binding post of the
battery and connect the red (+) probe to the Term inal 1 of the 4-wire connector of motor. The voltage
reading should be approximately 5V.
3. Use a multimeter set to 20V DC, connect the black (-) probe to the negative binding post of the battery,
he red (+) probe to the Terminal 4 of the 4-wire connector.
The voltage reading should be approximately 0V.
4. If the reading is incorrect, check the continuity between 4-wire connector of the motor speed sensor
and controller. If the continuity is ok, replace the controller.
5. If the voltage reading is correct, continue with the following operations:
5.1 Use a multimeter set to 20V DC, connect the black (-) probe to the negative binding post of the
battery pack and connect the red (+) probe to the terminal 2 or 3 of the 4-wire connector
on the motor speed sensor. The voltage reading should be approximately 0-5V.
5.2 If the reading is incorrect, check the continuity between terminal 2 or 3 of 4- wire connector and
controller. If the continuity is ok, replace the speed sensor.

(If you want run the motor, Jack up the rear axle of the vehicl so that the rear wheels are in the air)
Check Procedure 7G—Pin 13
1. Use a multimeter set at 20V DC, insert the red (+) probe of the multimeter into the Pin 13
(Red/White wire).
2. With key switch is turned ON, the multimeter should display 5V.
Connect the black (-) probe to the negative binding post of the battery pack.
3. If another reading is displayed, the following items must be checked:
• Continuity of wires in harness;
• Check whether the controller Pin13 has a 5V voltage output.
Check Procedure 7H—Pin 15 and 26
1. Use a multimeter set at 20V DC, insert the red (+) probe into the Pin 1 of the 4-wire connector of motor.
(White/Red wire).
2. With key switch is turned ON, the multimeter should display 5V.
Connect the black (-) probe to the Pin 4 of the 4-wire connector of motor.
3. If another reading is displayed, the following items must be checked:
• Continuity of wires in harness;
• Check whether the controller Pin 26(white/red) has a 5V voltage output.
