Flash Code #4 - Right Motor Disconnected

Symptoms:
! Four Battery Condition Meter LEDs Flashing
! Three Red LEDs and One Yellow LED
Diagnosis:
There is a communication problem between the right motor (8)
and the VSI controller (1).
Solution:
Use the following procedure to find the source of the fault:
1. Unplug connector 1b from connector 2a. See diagram 1.
2. Measure resistance across pin 1 and pin 2 on connector 2a.
See figure 16.
— If your multimeter indicates about 0.5 - 1.5 ohms, then re-
place the VSI controller (1) and retest the system.
— If your multimeter does not indicate about 0.5 - 1.5 ohms,
then go to the next step.
3. Remove the seat and battery box. Refer to the Go-Chair
owner's manual.
4. Remove the rear shroud, making sure not to pull out any
connected wires. See figure 12.
5. Unplug connector 2d from connector 8a. See diagram 1.
6. Measure resistance across pin 1 (red) and pin 2 (black) on
connector 8a. See figure 17.
— If your multimeter indicates about 0.5-1.5 ohms, then re-
place the power interface harness (2) and retest the system.
— If your multimeter does not indicate about 0.5-1.5 ohms,
then replace the right motor (8) and retest the system.
