Starter Brush Grounding Fix

[Curti]

This is a fix that an old friend with 40+ years in the auto electric business taught me. It is common for resistance to build up under the rivets of the end plate.  This is an Auto-Lite starter.  I would suspect Delco is similar. 

Rebuilders typically replace the brushes, bushings and bendix and fresh coat of paint and call it done.  It STILL turns over slow.

  I post this here because the ACD web site is working like a poorly grounded starter !
