Motor Brushes
The electric motors that power your Blast use carbon brushes. These
brushes may become susceptible to wear over a long period of time. The
motor brushes are the four 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 damage will
result. Failure to maintain the brushes could void the
warranty.
To inspect or replace the motor brushes:
1. Remove the seat and body shroud.
2. Unscrew each motor brush cap. See figure 27.
3. Remove the brushes.
4. Inspect for wear. See figure 28.
5. 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 Blast still does not power up, contact your authorized Pride
provider.
