Battery Charging or Drive Inhibit
Symptoms:
The power chair powers on, but will not drive.
The joystick displays "Battery Charging or Drive Inhibit"
error code when the on/off key is pressed. See Table 1.
The off-board charger is not plugged into the NE+ joystick
module (1).
Diagnosis:
There is an open in the inhibit circuit.
Solution:
Use the following procedure to find the source of the error:
NOTE: If the power chair is not equipped with a PTO harness
and a round 4-pin barrel connector, it will have a 14-pin run
plug (10) in connector 9e. If the power chair is equipped with
the 14-pin run plug, go to step 3.
1. Unplug the run plug (12) from connector 11b. See diagram
2 or 3.
2. Place a jumper between pin 3 and pin 4 of connector 11b.
See figure 14. Try to drive the chair.
WARNING! Jumping pins 1 and 2 could
cause sparking and/or cause the fuse in
the harness to blow.
— If the power chair drives, then replace the run plug (12) and
retest the system.
— If the power chair does not drive, then go to the next step.
3. Unplug connector 11a, or the 14-pin run plug (10) if
equipped, from connector 9e. See diagram 3.
4. Place a jumper from pin 1 to pin 9 on connector 9e. See
figure 15. Try to drive the chair.
WARNING! Jumping the incorrect pins
could cause sparking and/or damage to
the electronics.
— If the power chair drives, then replace the power take-off/
inhibit harness (11) or the 14-pin run plug (10) and retest the
system.
— If the power chair does not drive, then the power module (9)
may be programmed incorrectly. Verify the inhibit
program. See figure 16. The inhibit should be set to "High
Inhibit".
