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 Quantum Rehab Dealer.
