Motor Brushes
The electric motors that power your power chair use carbon brushes. These brushes may become susceptible to
wear over a long period of time. The motor brushes are the two contacts located inside the motor assembly that
supply power to the motor. They are designed to provide several thousand hours of operation. However, if the
brushes become dirty with carbon deposits or wear out, the motor will run poorly or not at all.
CAUTION! If inspection determines excessive wear
on the brushes, they must be replaced or motor dam-
age will result. Failure to maintain the brushes could
void your power chairs warranty.
To inspect or replace the motor brushes:
1. Unscrew the motor brush caps. See figure 30.
2. Remove the brushes.
3. Inspect for wear. See figure 34.
4. Replace brushes, if necessary. Contact your authorized Pride
provider for replacement brushes.
Corrective Maintenance
If the battery condition meter does not light up when you turn on the power:
n
Check the harness connections. Make sure they are tight.
n
Check the circuit breaker. Reset it if necessary.
n
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 Pride provider.
