What to do: Check the brushes to make sure that they are still making contact with the commutator. Contact manufacturer for brushes.


Likely cause: Controller may be defective.
What to do: Verify voltage is coming out of the controller.


2 - On initial installation, motor fails to start up,what to do?
Likely cause: Motor is incorrectly wired
What to do: Verify that the motor is wired correctly.


Likely cause: No output power from controller.
What to do: Measure voltage coming from the controller.


Likely cause: Motor is damaged and the armature is rubbing against the magnets.
What to do: Disassemble motor and see if the armature can be realigned by reassembly. Motor may have to be replaced.


3 - Motor takes too long to accelerate,what to do?
Likely cause: Motor controller not properly set.
What to do: Adjust the acceleration trim pot of the controller.


Likely cause: Brushes are worn.
What to do: Verify brush length.


Likely cause: Bearings may be defective.
