If you have taken the binnacle off at any time this could have caused a problem as well. If you don't get the electrical connection in the back seated all the way you'll get a "wacky tach." When I hit a bump it would spin around 360 degrees, stick in one position, or just not work at all. It was not only wacky, but zany and a little kooky as well. > ________________________________________________________________________ > ________________________________________________________________________ > > Message: 18 > Date: Wed, 07 Aug 2002 20:11:25 -0000 > From: "fluxmcfly" <bfreyguy@xxxx> > Subject: tachometer gone haywire? > > Can anybody tell me if there is a relay for the tachometer?
