Alternator Brush: Service and Repair

The generator's brush holder is integrated with the voltage regulator. The brushes are accessible for checking when the voltage regulator has been removed from the generator. The brushes should protrude at least 5 mm (0.2 in) from the holder when the voltage regulator has been removed. If they do not, install new brushes.

To change the brushes
1 Remove the voltage regulator.
2 Carefully unsolder the brush lead from the brush holder terminal while simultaneously withdrawing the brush from the holder.

Important : Work quickly to avoid heating the voltage regulator unnecessarily.

3 Carefully remove any traces of solder from the brush-holder terminal.
4 Install the new brush in the brush holder, insert the brush lead into the brush holder terminal and solder it in place.
