Should be two wire, works off of the ignition pulses, some outboard tachs did the same thing.

Did it work before? I wonder, could it ground through the mounting bracket?

It worked before. I traced wiring back to the coil, some one switched tack lead @ coil to the + side. I didnt pull the boat apart 3 or 4 years ago.. Works now, thanks Marcel
