Univolt replacement wiring?

[Pick]

Thanks Nick! That post explained a lot. My new Intellipower is in and running. I also got the Charge Wizard. The only thing that does not seem to work is the fresh water tank level guage. I may clip lead the gray wire, and see if it starts to work. Who knows, maybe a PO modified the wiring in the control panel. I mounted the old fuse board to a piece of angle iron, then mounted it in front of the Intellipower.

Mike, I'm sure you'll enjoy the low noise from the Intellipower. I leave my trailer for 8 months at a time, with the Intellipower connected to the 120v mains. After 8 months I return, and the separators are still covered with electrolyte. What a contrast to the Univolt! One thing I noticed with the fresh water tank level indicators is that the 4 level sensors are grounds, rather than positives.

Does anyone know what the gray wire attached to the little 4 amp fuse, goes to? The other end of the fuse goes back to the rectifier bridge in the old Univolt. I suspect it may just be for the indicator light in the front control panel.

It turns on the light in the control panel if the Univolt is powered. I just removed my Univolt from my 1975 Sovereign and it took me a few minutes to figure it out. This can't be duplicated on a two-terminal converter like an Intellipower--the battery will always be on the hot buss and you wouldn't want to put in the two diodes it would take to make it work.

Where can one purchase #4 and #6 Gage wire. Is it the same as I would get at Graybar i.e. a local electrical outlet. I noticed that the cabeling on my univolt is twisted coper not solid like #10 or #12.

#6 twisted cable can be gotten at Home Depot in different colors. They guy that put my lugs on my cables said that he has some really fancy 6 gauge cable that can be twisted into about a 2 inch radius circle. He also builds wiring harnesses and instrumentation for Formula 1 race cars, so he knows where to get the good stuff.

I don't think it should be too hard to find 4 and 6 gauge twisted cable. Finding the really flexible stuff could be harder. If you have the opportunity, get that, I didn't and it was a bit of a hassle.

By the way, I have the Iota converter in and working. I took pictures of the installation, it involved some changes to the original arrangement and I hope to have that up in a couple of days.

I had the same issue yesterday. A battery and a load wire, both positive, and a white negative came off the univolt.

The inteli-power has two sets of positive and negative connections. I assume to charge two batteries

I put one positive of the two positives from the univolt in the positive in one set and the other positive and the negative in the other set. It felt odd having a positive hooked in the set without a corresponding negative, but was not sure what else to do. The positive wires are very thick and it was easier than trying to double them up in one.

Should I take the one positive out and double it up in the connector that has the other positive and negative?

Thank you! Bill
