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.
To inspect or replace the motor brushes:
1. Unscrew the motor brush caps. See figure 31.
2. Remove the brushes.
3. Inspect for wear.
4. Replace the brushes, if necessary. Contact your
authorized Pride Provider for replacement brushes.
WARNING! If an inspection determines excessive wear on the brushes, they must be replaced or
motor damage will result. Failure to maintain the brushes could void your power chair’s warranty.
When to See Your Authorized Pride Provider for Service
The following symptoms could indicate a serious problem with your power chair. If necessary, contact your authorized
Pride Provider. When calling, have the model number, serial number, nature of the problem, and the error code if available.
n Motor noise
n Frayed harnesses
n Cracked or broken connectors
n Uneven wear on any of the tires
n Jerky motion
n Pulling to one side
n Bent or broken wheel assemblies
n Does not power up
n Powers up, but does not move
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.
