[Overdrive]

And what, of this assembly, would need replacing if it got harmed by the short? The rectifier? Seems like a bit much of an undertaking in any case, along with probably having to buy a few bearings, unless the OP feels confident in getting in there and doing the work. Maybe the dealer can rebuild it, but then it'll become a matter of which costs less -- a replacement part, or the labor and parts to do a rebuild.
