removehtml]The gauge on my fresh water holding tank always reads full when I turn on the instruments. I thought it might be the sending unit in the tank so I tried to eliminate that possibility by disconnecting the wires in anticipation of the gauge now reading empty or zero. Much to my surprise the gauge still reads full even with the sending unit completely disconnected. My next ploy is to try to cross the wires ... anyone heard of faulty gauges or a way to check sending unit .. much appreciated !!Error: Error: expected [/URL], but found [/removehtml] instead[/removehtml]
