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 Jazzys warranty.
WHEN TO SEE YOUR AUTHORIZED PRIDE
PROVIDER FOR SERVICE
The following symptoms could indicate a serious problem with
your Jazzy. If necessary, contact your authorized Pride provider.
When calling, have the model number, serial number, nature of
the problem, and the trouble 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 Jazzy still
does not power up, contact your authorized Pride provider.
