Default Re: Lazy Ammeter

I've got my doubts that the ammeter is the problem. Ammeters can go bad from over charging but what i've seen, they either work or they don't. If adjusting the third brush doesn't change the charging rate, the brush wires are reversed. It will motor and charge even if the brush wires are reversed but adjusting the third brush will make no change in the rate of charge. look at the left lower corner of page 66 of the new Brattons catalog for the internal wire hook up legend for the tube type model A generator. If the wires are reversed, like I suspect, it will burn out the field coils if allowed to operate in this condition for an extended period.
