Good to know.
My mom is close to someone who owns an auto electric (starters, alternators, etc) shop, but he's mostly retired.. he apparently "got wrapped up in those race cars and doesn't like to work anymore". Sounds like a good guy
She's going to talk to him, see if he would be interested in showing/teaching me how to rebuild the one I have.
Thanks for the response; will let you know how it goes.
