'77 Scamp Electrical Help Needed

I'm slowly working my way through my Scamp to-do list. Today I spent the day replacing the 12v wiring to my new LED lights and 12v recepticles. All went well, but I'm puzzled about the 2 posts under the sink. Why is this here and should I leave it alone? I guess my chief concern is risk of electical shock.

Also, I'm going to be installing a 100w solar panel next week. If I attach the solar controller to these two posts, can I charge and regulate the battery? I had planned to attach solar the standard way, directly to my battery, but just a thought that this would be an easier install if it would work. I'm clueless!

Also, I've attached pix of the 120w box. Its not pretty but everthing i working fine. Should I replace it or would it be okay to leave it alone? Any advice is appreciated.
I'm having trouble uploading the pictures, so it may take me a little while.

If those 12 volt posts are on fiberglass then they are insulated from each other, but it's also possible some metal object could touch them both causing a short. Looks like someone's home made setup. I'd eliminate them and do something better.

Just as a first intuitive guess is that someone set it up so an internal 12vdc supply or charger could be connected to it using alligator clips that are some times used on chargers??????? IF you have your battery connected do you read 12vdc with a test light or voltmeter?

That's what I thought too Mike. Don't know exactly what you'd hook up inside though?? I haven't checked with a voltmeter, but will do that tomorrow.

In your pictures, it seems 2 posts having wires connected there. If I were you, I would have visual inspect to see where those wires leading to. When hook up with towing vehicle, I would use volt meter to check if there is any voltage drop across them (it must be VDC). Besides, I woud have visual inspect to see where those posts housing on, mechanically. If without wires connected in them, just using Ohm meter to see if they are connected each other. It looks like those post were made from DIY project from previous owner for his/her own convenience( like charging battery or using as terminals for out-side source). About 120VAC, if I were you, I would re arrange wires to make them secured and safe also get rid off those wirings which lead...nowhere, for example. Just my opinion...

Thanks Randy. I'll trace the wires more thoroughly tomorrow and use my volt meter to figure out what I can. I first thought it was standard Scamp install, but after looking at pictures of other people's under sink areas, decided it was home grown. You can't tell by the picture, but they are quite large, probably 3+ inches. They are really in the way for needed storage. I had some items stored under there, and began thinking it wasn't a good idea because some items are metal. Wondered if they would short out if item touched . Since they're there though, I'm trying to think of any way I can benefit from them. Ideas welcome. I'm womdering if the former owner had a second battery under tne front seat attached to the posts.
I'm in the process of cleaning up the wiring and will be securing and removing wiring that goes no where (like the wound up red wires under the sink).

If I was a betting man, I bet they plugged the camper into 120, left the converter off, and plugged in a trickle charger and hooked it to those.

I'm close to done with replacing all my electrical (most wire included), some of the stuff I've found is just plain ridiculous, and some dangerous.

Awww, good thought Jared since there isn't a converter. Maybe his work-around for no converter. Seems to me though it would have been easier to add a converter. I don't know if all '77s came without converters-just wondering???? I bought it from the original owner and I'm very happy with it, but I'm having to learn as I go regarding the electrical system.

Is it just me, or has anyone else noticed the color? A white wire and a green wire? For 12 volts DC white is usually negative and black (or red) is positive. In 110 volts AC wiring white is neutral, black is hot, and green is ground. I'm confused.

Simple answer, people use what they have. I would stick a meter on it and check, but I bet it's 12v. which wire is which, is anybody's guess.

After what I've seen a factory will do, all bets are off.

Good eye Frederick. I thought that was strange too. One is green and the second actually looks grey to me. I got out my owner's manual tonight which includes a wiring diagram in hope of figuring out the wiring. Of course the wiring diagram shows green wires are for tail lights. So no clue there. My thought is that when the owner added this, "mod", he used whatever colors he had or were on sale that week.

Well below is the wiring diagram from mine which is a bit newer but Scamp isnt known for changing much over the years They do show a Green wire running from the 120V breaker box to the converter ground. Also some red wires where used for the TV booster which on mine also has the 12V plug built into it - does the trailer have a 12v plug in it? if not that may be what the red wires under the sink that are wrapped up went to.
