re: Camper Electrical Fun

you have 120 volt systems and 12 volt dc systems

the 12 volt dc provides both motive power for water pump, slides and
more importantly it provides instrument power for a lot of other stuff. Without a good house battery online you are wasting your time trying to analyze.

Standard batteries will run out of water and explode. Happened in my driveway and sounded like a hand grenade

Last summer, I found that my trailer battery was not getting 12V power to the lights. Battery was only 2 years old. I had checked / added water a few months earlier.

After checking fuses, I looked at the battery. The negative connection was very badly corroded.

A couple of years ago, my lights stopped working. I found the battery had no charge and the very old inverter was not putting 12 volts. The new inverter was about 1/2 the size of the old one but did not come with 4 fuses to run the trailer 4 separate curiets

After checking fuses, I looked at the battery. The negative connection was very badly corroded. I cut off the bad wire and all was good after reconnecting.

A couple of years ago, my 12V inside trailer lights stopped working. I found the battery had no charge and the very old inverter was not putting out 12 volts. The new inverter was about 1/2 the size of the old one but did not come with 4 fuses to run the trailer 4 separate circuits. So I had to take the old fuse panel out and install it next to the new inverter.

Also while doing this work, I added a 110V outlet to make it easier when doing work in the trailer.

I have some water damage now from a roof vent cover that had broken off and I did not find the problem until I saw the damaged wood. I will start that work next week, after this next cold weather. I hope this will only take a week or 2. I will have to remove a storage cabinet to replace the wall panel.
