When to See Your Quantum Rehab Provider for Service
The following symptoms could indicate a serious problem with your power chair. If necessary, contact your Quantum Rehab Provider. When calling, have the model number, serial number, nature of the problem, and the error code if available.
Motor noise
Frayed harnesses
Cracked or broken connectors
Uneven wear on any of the tires
Jerky motion
Pulling to one side
Bent or broken wheel assemblies

Corrective Maintenance
If the battery condition meter does not light up when you turn on the power:
Check the harness connections. Make sure they are tight.
Check the circuit breaker. Reset it if necessary.
Check the battery connections.
If the above conditions prove normal, you can load test the batteries with a battery load tester. These testers are available at automotive parts stores. Disconnect both batteries before load testing and follow the directions that come with the load tester. If either one of the batteries fails the load test, replace both of them. If your power chair still does not power up, contact your authorized Quantum Rehab Provider.
