Flash Code #3 - Left Motor Wiring Fault

Symptoms:
Three Red Battery Condition Meter LEDs Flashing
Diagnosis:
There is a wiring fault between the left motor (7) and brake
(7b). This can indicate a wiring problem between the motor
and the brake or possibly a short from the motor to the most
negative battery terminal (one side of each brake).
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 from pin 3 to pin 9 and pin 3 to pin 7 on
connector 2a. See figure 14.
— If your multimeter indicates an open for each test, then re-
place the VSI controller (1) and retest the system.
— If your multimeter indicates a short or a relatively low re-
sistance (less than 1M ohm) for either test, 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 2e from connector 7a. See diagram 1.
6. Measure resistance from pin 1 (red) to pin 4 (white) then
from pin 1 (red) to pin 5 (white) on connector 7a. See
figure 15.
— If your multimeter indicates an open for each test, then re-
place the power interface harness (2) and retest the system.
— If your multimeter indicates a short or a relatively low re-
sistance (less than 1M ohm) for either test, then replace the
left motor (7) and retest the system.
