I had to clean up the commutator on my ruby type starter motor, as it was a mess and sometimes refused to function. All fine, clean and cranking well. I left the cover off the starter motor while working, and noticed that there's sparking occurring as the starter motor is cranking- at the bush. Is this supposed to happen? I'm putting 12 volts through the starter incidentally.
Thanks
