How to troubleshoot Invacare Wheelchair that will not start?
If your Invacare Wheelchair won't start, there are several potential causes. First, ensure that the drive motors are engaged. If they are already engaged, the batteries may be defective and need replacement. Alternatively, the battery might be completely discharged, in which case you should pre-charge them.

What to do if Invacare Wheelchair motors stop and do not start again?
If the motors on your Invacare Wheelchair stop and don't restart, it could be due to a high motor load causing the power module to lower the voltage.

Why does my Invacare TDX SP2 Wheelchair pull to the left or right?
If your Invacare Wheelchair pulls to the left or right, it could be due to drive motors running asymmetrically. In this case, you should change the programming to synchronize the motors.

Lastly, check the cabling for defective contacts and replace them if necessary.
