I have been mapping what's on the 12v. circuits on my 2307C. I have not yet found anything that is on circuit #1. All the lights, vent fans, and outlets are on circuit #2. Is there something that I haven't found yet? What is the purpose for circuit #1?

According to a 2009 manual it is for the monitor panel, i.e. tanks and battery levels.

Thanks a lot! That was it. When I pulled the cover off the 12 volt distribution panel, I found that there were only 5 circuits wired up vs. the 9 listed in my owners manual. So I have been mapping what is actually on which circuit. I forgot that the test switch on the monitor panel had to be pushed to see if it was powered.
