My Electric System - Am I going to die?

According to the DC electrical diagram, the battery plugs into the fusebox (and not directly into the converter)????

EDIT: Nevermind, I understand now that the battery should be wired BETWEEN the Converter and the DC Fuse Block.

The DC fuse box is the thing with all the corrosion.

I'm hoping that's not the case :)

I'll test it this weekend.

Typical 12v outlet is a cig lighter socket like in a car.

No reason you couldn't add a fan once you get the wiring sorted out. I replaced my WFCO 8955 converter/charger with a Progressive Dynamics unit a few years ago to get a better charging curve for the batteries. The WFCO unit puts out 55 amps and still works fine, and it has a 12V distribution panel built in, but doesn't have the plastic case. See here.

If you are looking to re-do the wiring in the TT and upgrade the old converter you have, I would be happy to send you the WFCO FOR FREE if you pay the shipping. PM if interested.

Typical 12v trailer wiring:

Is there such a thing as a 12V "outlet" ?

I think mine is all hardwired directly to the lights and water pump. Was wanting to add a vent fan, but I'm probably out of luck.

A 4 flat is just stop/turn/running lights, a 5 flat has an extra lead for brakes. If you doing rewiring you may want to go to the standard 7-round that includes a battery charge line and backup light connection. Even though it's only 15' I would think that it would have brakes. Most states require them on trailers over 3000 lbs, but some are less at 1500 lbs or even 1000 lbs. If you are rebuilding this trailer to travel with, you may want to consider adding brakes if it doesn't have them already.

There are working TT electric hookups, so it has been rewired. It's a 4 or 5 way flat. I'm not sure about trailer brakes. My dad is going to look at it with me this weekend.

We'll be doing some interior painting while I investigate the electrical sys.

It looks like those fuses were for the running lights and stop/turn lights on the TT. The power would have been coming into that corroded fuse block from what was the tow vehicle cord, which looks like it was cut off. So that fuse block should be dead. Note the blue wire in that cut off bundle that doesn't go through the fuse block would have been for the electric trailer brakes. Is it connected to anything now?

So, first question, is there a cord on the trailer that plugs into the tow vehicle? If so where does it attach to? If not, you would reconnect a new one here. and as noted by westend you can get rid of the fuse block altogether.

The Converter is also your charger, and as noted probably won't do a very good job. Unless you can find a separate charger elsewhere but I am betting you won't. There will be fuses protecting the lighting and other 12V circuits in the trailer, they are not the fuse block pictured but must be elsewhere. They can be inside the converter or if not follow the 12V wires leaving the converter and see if there is another fuse block downstream. Although on second look it almost looks like the converter is not connected to anything with the red/yellow wires dangling. This unit may have been abandoned and replaced with something newer elsewhere in the trailer.

You need to keep looking in all the nooks/crannies and see what else you got there, these pics don't tell the whole story.

Bad news, you will die eventually...one thing about life is that nobody gets out alive....Good news, is that this isn't likely to be the cause!

I'm going to pull the trailer out from my storage spot and do the poking around tomorrow. My autosense multimeter should be in today.
