Speaking of electric motors Flatheadmurre, When my brother accidentally hooked up my 36 dodge pickup battery to negative earth the blower fan made very bad noises. It walked the brushes out of their cradles and did not blow , it was spinning backwards. If it hadn't been for that I wouldn't have ever known what he had done as the amp gauge was not functional. We re polarized the system and all was good again. No harm done just a good learning experience.
