All fixed! It was a combination of a bad part and poor memory. This is the part I absolutely hate. Humbling myself. Read on. Yes, I do believe that there was an issue with the remote and it's nice with the new one that can be programmed. Using a multimeter, the outlets were only reading 107 volts but when a load was put on the inverter, jumped to 115-ish. The tech from Magnum said there is up to a 5% variance on the inverter and I'm in range. All are working fine now. However.....SavnTheWhales is correct on which outlets are on the inverter and I was wrong. After much deep thinking and trying to remember about the outlets I mentioned, the lightbulb lit up. I had a note in my phone that had the listed outlets that I had mentioned and was stubbornly convinced that what it was for. Finally remembered why I listed those outlets. As previously mentioned, we had someone staying in the motor home for a couple of months over the winter and she used a couple of space heaters. She kept tripping a breaker so I went through and found out which outlets were on that breaker so the heaters could be on different circuits. The note that I had made was for that and not which outlets were on the inverter.

It was for which outlets were on a specific breaker.

I do know that the remote was bad because the outside tv and main cabin tv were not working on the inverter and are now. Finally have it listed for sale as I can't sell something when I have any doubts or concerns about something or if things aren't working right. Anyway, yes, I screwed up. lol Please forgive me irv2 community!
