I'm trying to figure out why my fuel gauge isn't working (hasn't worked since we purchased the boat). Seems to be wired correctly, and when I turn the starboard ignition on...the gauge goes from empty...to a false reading of 1/4 tank (no matter how much fuel is aboard)....if I turn on the port ignition...the gauge slams to far below empty. There is a switch, which rests in a neutral position, and is a momentary switch which is supposed to allow port "OR" starboard tank readings. All of the above happens when the tank switch is at neutral, and momentary port/starboard checks make no difference in the gauge readings.
The switch seems to check out fine....so is there a way to check the gauge and sending units?
