Idiot buzzer won't shut up
My 89 Comp has one of those "idiot buzzers" that buzzes when something is wrong on the boat (oil pressure, low volts, high temp). Recently it won't shut up. At first it would buzz, then shut up if we hit a wave, now it won't shut up even when NOTHING is wrong on the boat. I thought it was a loose connection, but everything is tight underneath the dash. Has anyone had theirs fail in such a way that it won't shut up? Any other ideas?
thanks!
