How to Troubleshoot a Quantum 600 Wheelchair With No Power

The Quantum 6000 power wheelchair uses a battery-powered motor to provide speed. With use, the battery or motor may wear down and require maintenance. The power module's connectors grow weak and require reconnection. If you have adequate upper-body strength, you can troubleshoot most of the Quantum wheelchair's power problems. However, many serious problems are caused by motor failure or malfunction. The motor may require repair or replacement, a task best left in the hands of experienced professionals.
