Default Re: Electric Wiper Questions

Thanks, guys. Vaseline I have in stock!! BTW, I've corrected my original post as I think it should have referred to the"commutator" rather than the "armature".

I've been doing a little research elsewhere online - saw that scratches on the commutator surface may cause sparking. I'm suspecting that I might have scratched it when I cleaned the slots. Will investigate and carefully buff the surface.
