MOTOR BRUSHES
The electric motors that power your Jazzy use carbon brushes.
These brushes may become susceptible to wear over a long pe-
riod 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. We recommend
that your authorized Pride provider inspect the brushes every six
months or sooner if your Jazzy runs poorly. If inspection deter-
mines excessive wear on the brushes, they must be replaced or
motor damage will result.

CORRECTIVE MAINTENANCE
If the battery indicator gauge 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.
