I am getting ready to run a couple 110v outlets, a light and a battery for my enclosed car hauler. Does anybody have a wiring diagram that I could use to help make sure I get it set up right?
Thanks in advance

Assuming that you know you will need two completely different wiring circuits for the 110 volt outlet system and the 12 volt system. Insure that you bring each of them together to their own breaker or fused panel for safety.

A couple of questions.

How are you getting the 120 into the trailer and what is it running?

What is going to charge the 12v battery and what is it running?


We have 120 volt plugs in our trailer, a convertor/distribution panel to keep the battery charged and to power any 12 volt items when plugged in to 120. We have a marine twist lock receptacle on the front of the trailer where we plug the 120 in, either into another marine twist lock on the motorhome to be powered by the generator or into a adapter cord so it can be plugged into a normal household socket. The 120 then runs into the converter panel and then to the plugs. The 12 volt runs from the converter panel to the battery and to 12 volt lights, furnace, etc. The battery is also charged by the tow vehicle but separated from the breakaway battery by the breakaway charger, so that the breakaway battery does not get discharged by lights in the trailer, etc.

120 will go into the trailer thru a typical RV 30amp cord. I have already installed door in the side of the trailer and have the cord.

Charging is one of the items I am trying to figure out. I was thinking I could have it charge off the truck. But being able to charge off plug in would be great! The 12v battery would be powering a radio (to hear the track announcer and tunes) A fantastic fan, three interior and two exterior lights.

The 120 would be powering a roof AC unit, Two interior outlets and 1 exterior outlet, 1 interior flourescent light, two exterior flood lights.. I would use either the Gen in the camper, a portable gen, or household/utility feed, depending on what I am doing and where I am.

This trailer is used for my daughters Jr. Dragster. I am trying to get it more like a mobile garage than just a trailer.

I would visit some RV salvage lots and get a converter. Run the 120V wiring using what is called MC, which is basically a metal clad cord. You could then safely use the MC to attach your 12V whenever possible. Run your 12V exposed in Red and Black. Whatever you decide, don't run any 120V unprotected or in a way that it can be confused with the 12V, it is deadly.

You should get a converter/AC panel used or new. With air conditioning, etc. you will need to separate the circuits and have curcuit breakers. Plus you will have a fuse panel for the 12 volts stuff and have a way to charge the battery.

That charger is for maintaining the battery when not in use. If you want to keep the battery up while using it, you will need a better charger, or even better a converter. SWMO gave a good suggestion but buying a used conveter from a RV salvage yard. You can get newer to old ones for a fraction of the cost of a new converter.

Ok, searches and phone calls to the salvage places turned up many but they were almost the price of new.

Found this one here Converter/charger

Am I getting back on track now?

Hi:
If you are shopping E-Bay........ do a search for an "inverter/charger" rather than a converter/charger. I believe you'll have a larger selection.
