1993 Mariah Diablo Wiring Issue
 
My boat was running fine till yesterday. I got to the lake and it would turn over and briefly start. I then noticed that my gauges were not working at all. The lower controls..bilge, lights, horn all worked fine. I thought maybe it was the ignition switch. Replaced that....same problem. Guessing its a ground issue. Not sure where to look.

Thanks for your help.

Is your battery and alternator in good shape?

When I replaced a blown fuse, I accidently knocked a wire off ignition switch post. All is well. Thanks.
