I de-winterized our trailer,and we took it out for the first time since last fall. Everything was working normally in the driveway.
Got unhitched and set up at the campsite. Opened the door and heard the propane detector going off. Thought that was weird and before turning on any lights or appliances sniffed around for a leak.
Didn't find anything so I flipped on the lights. The lights were very dim. I checked the battery level with the little dummy sensor used to check black/gray water levels.
All the lights on the panel flickered a couple times and went blank. I had lost all 12V power in the trailer. The only thing left working was the landing gear which is wired to a 50A circuit breaker and then to the battery. The landing gear went up and down with no sign of low/dead batteries.
I plugged into shore power and everything started working properly. I spent some time checking everything I could think of trying to work out the lack of 12V in the trailer.
I was having some coffee Saturday morning when I started to hear a clicking sound. I traced it to the 50amp circuit breaker connected to the landing gear. It tripped and reset about a dozen times and stopped. Checked the landing gear and now they don't work.
Got home last night and started digging around again. I've tested and re-tested everything I can think of. The only thing I've found was the bad 50A circuit breaker. I replaced it this morning and the landing gear is again working correctly
The converter is putting out the correct voltage. All fuses and circuit breakers test good with a test light,and multi-meter. The batteries show correct voltage and test good with a battery tester. Battery connections are clean and tight.
Everything continues to work properly on shore power,and nothing except the landing gear works on 12V
At this point I'm stumped. If anyone can think of something I maybe missed,I'd love to hear it.
I'm going out shortly to pull down the underbelly plastic and see if there is a fuse or circuit breaker I can't see.
