Larry Weidner told me there were three terminals as you did. I showed him the panel in my 78 Royale. And my extra broken panel out of a Royale. Both have just two terminals. Bob Dunahugh





Gauge shows full all the time. Pushed the LP gauge switch. Had 12 volt on both the terminals on the back of the gauge. ( Both the red, and white wires are not connected to the tank sender. ) The white wire at the tank, But not connected to the tank sender. Is a true ground to the body. Next I need to engage the LP gauge switch to see what voltage I have at the red power wire at the tank. Shouldn't the voltage at the tank be lower? If I have power at the tank. Attach the ground to the ground terminal on the tank. It should work. If not. I need to check continuity in the sender. Bob Dunahugh 78 Royale
