Casita electrical question

Hi... I've just joined the forum, since I've just bought a 17' Casita Spirit Deluxe 2008. One of my first jobs is to install some extra wiring for 12 volts, since we like to camp without hookups and I will be using LED "bulbs".

I see one 12 volt receptacle. Is there a place where I can tap into to run a couple more 12 volt lines, e.g. for reading lights above the bed, and light on the dinette table?

I cannot find an archive or a way to search previous posts on questions like this. Can someone enlighten me? Many thanks, David

If you can get access behind the 12v outlet you can tap into it. Removing the lights will give you more access to the wires and possible other locations. Just remember your draw capacity of any new outlet maybe limited and less than what you want. The ideal way is to run a dedicated, fused 12v line from the converter, if possible.

Welcome here.
Why don't you just replace the 12volt bulbs in there right now with LED's as many of us have and call it a day?

If its not broken why fix it?

I try to leave the 12 VDC accessory outlets as stand alone circuits and either splice into existing lighting circuits, or just run new wires from the converter to where I need power.

I do this because, with my luck and experience, the fuses on the 12 volt outlet circuits are the ones most often blown, either by overloading, say when you are using an inverter, or by problems with what I will call "Cheesy" quality in many 12 volt plugs. That way, if an outlet fuse is blown, you are not left in the dark trying to fix it.

As mentioned, the best way is to run new wires for new lights. However, as LED's use so little power, there usually isn't much concern about overloading existing lighting circuits if you choose to splice into them.

BTW: When I say "Splice", I mean to use regular crimp-on wiring connectors and a real crimping tool. I'm not a fan of plier type crimpers or ScotchLoc type connectors, and wire nuts are a real no-no.

LED lamps

I appreciate the comments and I'm really glad I discovered this forum! It was by accident.

The '08 Casita (to be delivered tomorrow!) has a neat lamp on the dinette table, and I'm pretty sure it's 110 volt. So I want to change the wiring for that to 12 volts. I gather there are adaptors from the 110 volt screw socket to the sort of base one finds on an 1156. So I will be looking for such an adaptor.

I also want to buy a three-stage charger. On my previous camper (Aliner) I replaced the cheap charger with a WFCO 3-stage charger. Do folks with fiberglass RVs do anything like that? Does anyone know what sort of charger comes in an '08 Casita? I presume it's not a 3-stage charger. Any suggestions on charger to buy? Many, many thanks! David

You can not change a 110v lamp to a 12v by replacing the bulb. It is probably a 12v lamp that you can replace with led bulbs, it is already 12v. Randy @ Best Converter is the guru and can advise you of what you need BestConverter - Converters, Inverters, Electrical Supplies, Electronics

IMHO: Sorry, I consider the WFCO products to be the electronic equal to the Yugo. Yes, it's a converter, but again, in my opinion, that's about all.

Having had three out of three WFCO's fail within the first year I will no longer install them when asked. I prefer and use the Progressive Dynamics PD-4045 wih smart charger, 12 fused DC circuits and a AC dist bay big enough for 4 or more a/c circuits. Usually less than $200 on eBay. I have installed 7 with the only issue being a wire that was conneted for Canadian standards on one unit that had to be moved.

Hi David,
I don't know if this would be helpful but on the Casita Travel Trailer Forum you can download Gene's Casita manuel which contains the schematics for the wiring. You need to be a member.

Good luck,
Kathie

Unless the PO has made mods, all the lights will be 12v. At least tney are in the 09. We replaced the bulbs in strategic areas (6 of 10) with LED using the 1156 replacements ` $5 10 online.

great comments... thanks!!

Good comments all. It's really nice to find a forum where people actually reply and try to be helpful! I'll contribute anything I can.

Tom... thanks comments on font. I'm glad to hear about the Progressive Dynamics charger and will look into it. I wasn't very impressed with the WFCO charger I put in my Aliner, but didn't know about any others.

I'm told the lamp on the dinette table is 110 volts, but I will check it. It looked like a 110 v bulb. I will change the wiring to 12 v, and I've ordered a couple of LED 12 v replacements, but with an 1156 base... I had previous experience with those. So I will find an adaptor and that should take care of that. David

Jumping in and making a lot of electrical modifications might not be the best of ideas. I would suggest that you use the trailer a few times before making changes. You could have enough light without the changes or without the use of 120V. Once you determined what you really need then make the changes. However changing the 1156 blubs to LED is a good idea.

Bob could you clarify what the differences are in Canadian and US wire standards? Curious as I wasn't aware there were any that would impact a new charger install.
