Hey all -
Helping a buddy find and fix a starter / electrical issue. We isolated it to the starter 12v post which, when tested without any connections (but still on the bike) is shorted to the chassis. Can someone confirm that's not the way it should be. I'm 99% sure.
I assume the issue is whatever isolates that post from the starter housing is broken or misaligned. The rubber washer on the outside is still intact. But the post was loose before we tightened the retaining nut on the rubber washer. I'm betting the problem is on the inside. If so, is that repairable? Or new starter land? Eg can the starter be opened up?
Thanks!

First off, the starter post to ground will be a very low resistance even when good. You don't say how you determined it is shorted to ground or what symptoms you are having to believe you have a bad starter. I've never checked a known good starter to ground but I would not be surprised if I got 2 ohms or less.

Thanks for the reply. It was very shorted. Took the starter apart and the square insulating plastic piece inside was shattered.
Combination of checking all the relays and realizing the load shedding one was not performing, despite it functioning correctly - led me to the starter wiring, then the starter.

I've read of this problem (shorted starter) one time before on either this forum or another (can't find it now). Same problem; same solution.

Check the parts fiche. Buying a used starter and renewing it may be less expensive.
-
Yep. Just shy of $30 worth of parts to fix er up. Vs 420 for a new one
-
Going for new brushes too while it's apart?
-
That was one part of the part to be replaced. Then yep bought the other one too.
