Starter motor questions - rebuild

[jondee86]

When the solenoid moves the gear out, it also makes a contact to switch
power to the motor. So, if solenoid moves but the motor does not turn,
there are two possibilities...

1. The solenoid contacts are not making a connection, or

2. The carbon brushes on the motor are worn down and no longer
making a good contact with the copper commutator. This one can often
be temporarily fixed by giving the body of the starter a sharp crack with
a small hammer or similar tool.

This shakes the brushes enough to get then to move fractionally, and
make a better contact. Still needs fixing by replacing the brushes :wink:



B and M are the contacts that make to put power on the motor.
S is the small wire that supplies power to the solenoid.
