MOTOR BRUSHES

The electric motors that power your Jazzy 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.Remove the seat and body shroud.

2.Unscrew the motor brush caps. See figure 17.

3.Remove the brushes.

4.Inspect for wear. See figure 18.

5.Replace 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 Jazzy’s warranty.

CORRECTIVE MAINTENANCE

If the battery condition meter does not light up when you turn on the power:

νCheck the harness connections. Make sure they are tight.

νCheck the circuit breaker. Reset it if necessary.

νCheck 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 Jazzy still does not power up, contact your authorized Pride provider.
