Can anyone tell me how to check my guages? I mean, check the guages and instruments to determine if they are functional. Then, if the instrument is good I can track down the problem elsewhere, such as wiring.
My Battery Check guage usually does not read above fair. When I'm hooked up to shore power the needle is just crossing over into the bottom of the good range. It's a new battery and I don't have a problem with not enough 12v
My Ammeter needle never moves.
Both my Battery Check and Ammeter have horizontally mounted needles that rise or fall vertically. The front of the guages are clear convex plastic.
While I am at it my water level and holding tank indicator "christmas trees" don't read, although I am guessing the problem is in the probe/sensors.
