We have a 2006 Casita Spirit Delux that is receiving 12v charge from our TV, but the charge is not getting to the battery. The Casita Owners Manuel shows a fuse near the battery but I can't find it. Any ideas?

Yeah, I found that one when I was installing a new converter. But I thought it was between the batteries and the converter. Not between the TV & the batteries.. Anyway It was external to the battery box mounted on the outside of the box. I don't remember if I had to remove the seat to access it or not.

What size of wire on your tow vehicle? It must be at least 10 gage, 8 gage is the best. If it is 14 gage, the wire is too small for the current to flow.

Remove the cushions, or prop up the bed, over the bench on the street side, Lift the top cover to expose the battery box. On the side of the battery box with black wires attached is a 20 amp fuse module. My understanding was that this is a re-settable fuse, which is sorta like a self resetting circuit breaker. If it has failed in the open mode your battery will not charge from the tow or from the converter.

If your battery charges when connected to line voltage then this is NOT your problem, but don't be fooled by lights and fans working while connected to line voltage, they are powered from the converter.
You should also check battery terminals for corrosion.
Hope this helps.

On our 1999 17' SD it's necessary to remove the street side bench because the self resetting circuit But fbreaker is mounted to the rear side of the battery box. Not where the battery is but inside under the bench.
First I would make sure the battery is properly connected BLACK TO PLUS, and is good. If it's the original to your 06 consider it bad.

If you know how to use a Voltmeter,Do a voltage test at the casita battery when hooked to the tow vehicle and running.... It should jump up to about 13.5 +/-Volts vs. unhooked with about 12.6 +/-. If your not good with voltmeters go into wal mart next to the car batteries and they have inexpensive voltmeter that plugs into the accessory plug in your casita. after that test do another with it plugged into shore power to see if the converter is charging properly.

Simple test. Turn your inside lights on when plugged into shore power, are they nice and bright? Now un-plug your shore power plug, do the lights get dimmer.? Proves, your convertor / charger is working and your battery may need replacement if the lights get really dim. It also proves the circuit breaker is not open. The circuit breaker talked about is a self resetting automatic circuit breaker in series with the battery positive or in this case Black wire. I've been working in the electrical related trades since 1962, never seen yet a resettable fuse. A #12 or even #14 wire coming from your truck assuming its been working before and does not have connection issues is enough to charge your battery. Not enough to charge your battery and carry a large load as running your refrigerator on 12 volts however.

On my recent trip in September I found that my battery as not charging also , same year and model Casita as yours, and it had me concerned. I found that when my battery was inserted, that the contacts were not tightened enough. This caused them to be on and off while traveling causing the battery to not charge properly. After checking everything I discovered this mistake and tightened them properly. After that I never had a problem. This is just one thought that may cause your problem.
