Univolt?

Is this my Univolt?
The wiring is an absolute mess. Most of the wiring is dried out and cracked. I don't have a clue of what wire is what and where any of them are going. I don't think it charges the battery when plugged in to AC. I have been using a small 3-step charger to keep the battery topped off. So far not a real big issue as I have been doing only camping where I have been plugged in. Plans are for battery upgrading to two G27s, solar panels and a new converter/charger, anticipating some extended boondocking in the future.

Looks like an old converter. Also looks like it's time to replace it.

I am guessing that it is original from 1964. Updating the electrical system is on my short list of things to do. Any suggestions on what would be a good converter to consider that would not break the bank?

I installed a Progressive Dynamics 9245 in our Argosy 26' and and happy with the results. Bought it on the Internet.

The 9245 seems very popular here. I found a lot of post from members who had used it. As far as I can tell most seem very happy with the results. Also the price seems reasonable.

Call Randy at Bestconverter.com. Based on recommendations from this forum I called him and he set me up with a new three stage 60w converter, about $150.

Ok, the mess of wires you are talking about. Pictures? I would expect to see at least a white, pink, yellow, blue and maybe black or brown wires coming out of the wall. Try to get post a picture of them.

It's always interesting to see other similar vintage rigs to compare: our 1964 Globetrotter has what looks like the original Univolt but the wiring is very neat and intact. I want to use Gel batteries so we're going to change out to an Iota DLS55 that can just be swapped out with the Univolt. I'm going to pay someone to do it, rather than tackle it myself- Adam Blair in Benicia. The original univolt doesn't charge when it's plugged into AC, just when you're towing.

Globie, does your Univolt look anything like the one in the picture I posted?

Awchief, no, it doesn't, other than the color, and you can see some of the plates through an opening in the side of ours. I thought that ours was original, but the original owner may have replaced it. The 120/12v/polarity switch box looks the same though.

Strange, I figured that our trailers would have basicly the same systems thru out. Airstream seemed to just grab what ever was on the stock room shelves when they were putting units together. No rhyme or reason to some of the assemblies.
I guess I will just have to go ahead and buy a new converter and try to figure it out once it shows up. It really throws me that I have no fuses of any kind in my trailer other than the two AC circuit breakers.

Univolt?

Greetings AWCHIEF!

The gray box in your photo closely resembles the original Univolt that was taken out of my Overlander shortly after purchase. That Univolt liked to boil the electrolyte in the battery, and it failed entirely during my first trip in the coach. If that Univolt is similar to mine, that raised back cover is held on with between two and four screws . . . and when removed reveals the 12-volt fuses (glass automotive type contemporary to the coach).

I suspect that the source of many of the components utilized in our coaches changed over the model year to reflect acquisition of different suppliers and/or the availability of improved yet similar equipment. Also, there are quite often differences between coaches built in Ohio and coaches built in California.

Good luck with your electrical project!

Kevin
