No, the converter is what converts AC power to 12 volts to run everything and charge the house battery. The battery isolator keeps the 12 volt circuits in the rv from running down the starter battery.

It sound like your converter isn't charging your battery and your isolator isn't isolating the two systems.

Since no one has responded to your schematic request, I think your going to have to trace down the power distribution circuits in your RV and draw your own schematic. You seem to know your way around a DVM.

I've done several, it just takes time, and once done you'll be able to figure these type of issue out quicker.

Thanks for the info. So, I am assuming the Converter is somewhere inside the electrical control panel... I haven't opened it up beyond the latch-door just to check the fuses.

So, how would I go about testing it? Hook 110v to the input side and test to see if it is producing 12v?

I went ahead and replaced the Controller... I already paid for it, mine is almost 30 years old, and they probably won't take it back anyway, so why not. But if the controller is bad, I wonder what would have made it go out right after I got it back. It still just seems strange to me that the previous owners had it all these years, kept it well maintained, had it plugged in for a long time at their place with zero issues. Then, as soon as I get it back from the shop I took it to for a thorough going-over, change fluids, fix a few broken things, it comes back and this electrical headache rears it's ugly head. I have to think that someone along the line at that shop did something to have caused this.

I'm not looking for blame; I'm just looking for a solution and understanding of what happened so I can hopefully prevent it from happening again.
