Should you fail to align the slip ring and brushes they is likely to make inadequate Speak to and use abnormally.

This tab connects straight to among the brushes in the alternator. In case you poke a small screwdriver or other ideal probe via this hole and floor this tab, you are able to bypass the regulator as well as alternator will head to most output.
