Monitor Circuit Blows Fuses

in that the monitor panel is hot and the guages all goto ground

if its NOT the water pump, or pump controller, or water heater switch

then one of the sensors as shorted to ground OR the wire to the sensor has shorted out
fw, black tank, gray tank

Now that's interesting. The monitor panel is completely dead. Nada. The shorted load-side wire at the monitor fuse is white/brown. I pulled the panel and disconnected the only white/brown wire that was back there. Still shorted to ground at fuse. That tells me that the short is somewhere "upstream" of the monitor panel and the sensors. Either a rubbed through wire upstream, or a faulty/shorted component that shares that circuit.
