So my speedometer is not working. Can I just unscrew it from the trans and clip it down in my drill and spin the drill to test? Anything else to test? Any thing else comon cause them not to work? Did I just not plug it in, or did I cut something in the dash cluster when hacking cluster for custom gages? I though it was just cable driven though?
