Flash Code #10 - High Battery Voltage - Pride Go-Chair Technical Troubleshhoting Manual

7. Measure resistance across pin 4 (white) and pin 5 (white)
on connectors 7a and 8a. See figure 22.
— If your multimeter indicates about 60 ohms for each test,
then replace the power interface harness (2) and retest the
system.
— If your multimeter does not indicate about 60 ohms for
either test, then replace the corresponding brake (7b or
8b) and retest the system.

Flash Code #10 - High Battery Voltage

Symptoms:
! Ten Battery Condition Meter LEDs Flashing
! Three Red LEDs, Four Yellow LEDs, Three Green LEDs
Diagnosis:
The total battery voltage is over 32VDC. This only appears if the output of the charger is over 32VDC.
Solution:
Use the following procedure to find the source of the fault:
NOTE: Make sure the only chargers used on the Go-Chair are Pride Mobility chargers. All of Pride's chargers are "smart
chargers," meaning when the batteries are fully charged the charger stops charging them. If a non-Pride charger was
used, the batteries may be overcharged.
1. Remove the battery box. Refer to the Go-Chair owner's manual.
2. Plug the off-board charger into the off-board charger port (connector 3a) on the battery box. See diagram 2.
3. Measure voltage across the positive and negative battery contact pads (5e and 6d) on the underside of the battery box. See
diagram 2.
— If your multimeter indicates less than 32VDC, then replace the VSI controller (1) and retest the system.
— If your multimeter indicates more than 32VDC, then replace the off-board charger (9) and retest the system.
