Not sure if I'm in the right place, but we are having a problem with our Jayco 19H. I brought it home last week and plugged it in to the garbage to get the fridge cold. Everything worked fine… (I thought) We get to the camp ground and plug in to shore power around noon and by that evening all the lights were dim and an alarm sounded. The camper seemed to be running strictly off of battery not shore power. The owner of the camp ground did a quick fix and hooked up a battery charger then plugged that in to shore power and that got my through the next day. Any ideas on what this could be? I have read about the converter… Could this be it? If so, is that an expensive fix? Thanks for any and all info.

I think the converter is in the panel behind the fridge. Remove the harness on the 12vDC and ground, plug in the trailer, put a multimeter across the terminals and see if your producing DC current. I doubt the converter is too expensive but then again it is a trailer product.

A quick way to see if you battery is receiving 12-14VDC from the TT's battery charge controller is:
- Unplug TT from shore power
- Go to the main 30 amp fuse by the battery box.
- Pull the fuse
- Take a voltage meter like Roy posted
- You should read a voltage on the battery side of the fuse holder
- No voltage on the TT charge controller side
- Plug in to shore power
- Should have 12-13+ VDC on TT charge controller side and battery side
- If there is no voltage on the TT charge controller side
- Check the reverse polarity fuse and main 12VDC fuse in the controller

Not sure of your AC electrical skill level so I am not going to go into the AC portion of the controller.
