A few days ago I posted about the 1200 mile junket over the Easter weekend and how well the now broken in S&J engine was performing in the Royale. I also said that while on that trip we encountered an electrical glitch that caused the lights on the drivers side in the bedroom, bathroom and kitchen to stop working.

While probing yesterday to find out why I also found that the master ground at the house fuse box was not providing a reliable path to ground even though all the circuits other than that one light circuit seemed to work fine. As I dug further I found that last summer while swapping inverters to find out why the Panasonic Inverter microwave was drawing too much power to run off of either of the inverters in the Royale and the Clasco (it draws waaay more amperage than the name plate states) I must have lost the end of that fuse box master ground and did not connect it to the shunt as I thought I had. It was just laying loose buried under a pile of stuff under the inverter where I could not see it. Somehow all those circuits were finding a path to ground somewhere, just not a reliable path to ground, and that was the root cause of the electrical gremlin. That was why the voltage at the furnace was off and unreliable and why the lights stopped working unexpectedly. It also e
xplains why the battery monitor seemed to show such a slow discharge rate. It was not seeing all of the draw from those house circuits which included lights and the furnace after I rewired it. It was seeing the draw from the inverter so it did show the batteries going down while parked, just not as fast as I thought they should be going down.

All is well that ends well, I guess, but it hurts a bit more when the wound is self inflicted! I am still curious as to where/how all those circuits were finding a path to ground on their own all this time from last summer to now. Must be 40 years of adding a ground to the aluminum ribs or the frame here and there.
