Bought a 2002 Bayliner last year. Great shape; professionally maintained. Only one problem, a false alarm.
Boat runs great all day until I turn on the nav lights (note: this switch is nav lights only, doesn't include anchor light). Then, the fuel gauge goes to zero within a few seconds and the temp gauge goes to max also within a few seconds. An annoying alarm accompanies the wayward gauges. I am absolutely certain that the engine isn't overheating and that the fuel tank hasn't gone empty ... as soon as I turn the nav light off everything goes back to normal within a few seconds.
Sounds like an electrical problem to me, not that I know much about electrical problems. The nav light switch is a Carling two-tab on/off switch. The upper (really it's in the center of the switch) tab has a single blue wire labeled "14" connected to it. The lower tab has three lines connected to it: a blue wire with a yellow stripe labeled "13", a grey wire, and a grey wire with a blue strip. Hopefully those labels and colors mean something. I'm wondering if somebody just hooked up the wires wrong.
Any suggestions or can someone point me in the right direction?
