Thanks to everyone who replied trying to help. Turns out it was a simple fix. I had tunnel vision focused on that relay and control board. I just didn't notice that somehow my converter had been switched off, therefore the batteries weren't being charged. No telling how long that had been going on. They had been hot enough to start the coach and move several times, and charge off the alternator, but it finally sat long enough for that relay to start acting up. I put all batteries on a charger, and turned my converter back on. Amazing how everything works now. And apparently that board does drop the relay voltage to 6 vdc once it energizes. Thanks again.
