I bought this boat and the tac
I bought this boat and the tach doesn't work.I have 12v & ground at tach. Alternator works so I assume rectifier OK. How can I identify signal wire at motor to check continuity to tach? Also can I read a signal on the wire with a vo meter?Any tips would be greatly appreciated. David
