Clicking noise-converter or?

[m.nolte]

I have a '67 Sovereign that is currently plugged into the house. I noticed this weekend when we were working on it that there was a clicking sound coming from under the bed, where the battery and 12v system are located. The clicking appears to be one of the resetting 12v circuit breakers cycling on and off. I ordered and replaced all three of the circuit breakers but they continue to cycle on and off. But it only happens when all the 12v fixtures are off. If I turn on 2 or 3 lights the circuit breaker quits cycling on and off and the current seems to smooth out. (no more flickering at the lights). All the 12v systems, including the Univolt are original. There is no battery currently installed. No other breakers AC or DC are tripping. It seems to only affect the one circuit breaker that serves the back half of the trailer (bathroom, bedroom lights and reading lights above bed).
Could the converter be oversupplying and causing that circuit breaker to heat up and cut off? (I ask because when you turn on the lights and start to use some 12v current the problem stops)
Is it as simple as needing a battery to smooth the current? And if so, I have read several times that the Univolts will cook the battery. So it seems as though I would need both new converter and battery?
Any thoughts or suggestions?
Thanks!

What you have is a short circuit. The 12v+ current in that particular circuit is going directly to ground. That heats up and opens the breaker, then the breaker cools down enough to reset, and the cycle continues.

It's really not good to leave it like that.

Thanks, we have it unplugged just in case. Don't want to catch the trailer on fire or make anything worse. With a short, I'm guessing the only thing to do is to put a meter to it and try to trace it out?
