Starter Brush Holder Test

1. Check that there is no continuity between the O+ and O brush holders.
If continuity exists, replace the brush holder assembly.

2. Insert the brush into the brush holder, and bring the brush into contact with the commutator, then attach a spring scale to the spring. Measure the spring tension at the moment the spring lifts off the brush.
