Just installed my SeeLevel 709-4P and I'm having a problem. Everything works just fine until I hook up to shore power, then the system shows a short at all sensors. The tech guy at RVgauge thinks the converter is taking the battery out of the loop somehow, but my volt meter shows that isn't the case. I've rewired just about every way I can think of, and even tried running a set of wires directly from the battery to the sensors, which worked. But the normal setup isn't working. And yes, the old gauges worked fine. Any suggestions?
