no man its cool i understand you have alot of good information to tell so tell it, im just saying what i know, i rebuild alternators all the time, power window motors to really any electric motors. and yea a couple i have rebuilt have failed , but thats only a couple and sh!t happens.since i own a glass shop i set in my basement every night rebuilding darn motors. and its well worth it, when you can get them for free rebuild them and sell it for 150$ why not?
