Starter on 94 sidekick strange cranking sound

[zukitrek]

Yes it looks that way, right? But somehow she's been firing up ever since. I did skip telling you that, before I fired her up that day, I had opened it up again, sanded commutator segments and cleaned grooves as well as solenoid contacts. Was that a factor on it working again? I don't know? Why did it fail all those days? Intermittent failure? Who knows? I do know that right now is working. Maybe the next crucial time it is going to fail big time? But I can not get a new starter now, not yet. Booster now is failing, failed or something else. But I do know it was also affecting performance (not related to starter, but to idling). Plugged it and car idles just perfect timing spot on as per FSM rules.

Will let you know.
