To begin with, this may not be the right forum. If not, I apologize. My speedometer was working. It has since stopped. New cable, so I don't think that is the issue. I do remember that a few eeks back, I was drilling a hole in the dash larger for a different size cable. I was near to the dash cluster and using an electric drill. As I drilled, the speedometer registered 30 mph or so. Is it possible that I 'degauzed" the magnets in the speedometer? If I messed it up, can I fix it, or should I just get another 56 Speedometer? Help!
