Photos Of Converting From Univolt To Intellipower/New Converter

I believe that I have a pretty good handle on how I am going to swap out my old Univolt for my "new" (newer) PD Intellipower but I would like to look at some photos of prior swap outs rather than just relying on diagrams from the service manual. I see references on posts to these pictures but have been unable to locate them. Where might I find something like this on the Forums? Thanks. Montanaandy

Good question, I have made the same request several times with no response.

Unfortunately, not all AS used the same Univolt and fuse system over the years, so one set of photos will not tell you everything you might like to know. Some Univolts had the fuses inside, some used panels outside of the Univolt. When replacing it with a PD converter/charger a new fuse panel is often necessary. For those Univolts with internal fuses you must do it, and not a bad idea for the AS products with an external glass fuse panel. Those tend to get tired and fuses overheat. That is because usually the fuse clips are riveted to the brass buss bar, and the rivets get loose.

I could post photos of my three rigs, all with PD converters, but I am not sure what they would show you. Each installation is a bit different.

Photos...

Got it. I did not realize that there was that much variation among Univolts in the various AS models.

I still would appreciate it if you would't mind posting your pics. It will give me a visualization that I can personally work with much better than a black and white diagram.

I do plan on installing the fuse panel that Vintage Trailer Supply sells on their site and replacing the fuse panel on the existing Univolt (where ever that may be on the Univolt in my 78-31" Soverign). As I mentioned, I do have a diagram that VTS has one their website which shows how to sub in the new fuse panel with the Intellipower, and I also have the service manual for my trailer, but I am more of a visual guy and if I see a picture of something/have a pic of how something should look this works better for me.

Thanks. Montanaandy

I just got the PD 4560 All in One for my trailer. I have asked for pics ( I am also visual) and help on the rewiring with very little response. I am rewiring the whole trailer with 6/2 stranded for the 110v 50 amp main, 12/2 stranded romex (yellow) for the AC and 12 awg duplex for the DC. I have most of the wires run for the ac and dc along with the main. I am a bit away from actually going "live" with the converter. I still have to finalize a couple things. I will post whatever I can for you but I would still like to see other setups so I will be following this thread. Oh an the install instructions for the PD 4560 are useless crap!

Only pictures I have right now are of the old wiring. I am still a ways out on the new install. But will be glad to post pictures....if you can wait 6 months or so.

I don't have pics but when I converted my 1978 Ambassador about 9 years ago it was an easy swap. The univolt was heavy to get out but the conversion to the Intellipower was a breeze.

I have a 66 TW. The fuse panel is separate from the univolt. I replaced the univolt with a PD 45 amp model I believe. It only took about 30 minutes. I have not changed the original 12v fuse panel yet. It works fine. I want to change it out with either a VTS panel or the marine Blue Something panel. When I can get myself straight on wiring for the 12v panel, I will upgrade it. I will post photos of my univolt replacement within the next day or so.

Mine was a pretty simple swap. It's in the front behind the sofa. The fuse panel is separate, mounted in the wall above. There are some pics here: http://www.airforums.com/forums/f449...0-a-57567.html

Hope it helps some.

That's exactly how mine looked. Easy swap.

Here is mine in the bath closet of my '75 Argosy 28. My PD9260 is sitting on the shelf temporarily, until I do the plumbing. Then I will place it under the shelf on the floor. The fuse block has 3 of the 10 connections used with 15 amp fuses. The blue wire has a separate 30 amp fuse, to the tongue and tongue jack/charging from tow vehicle. The black fuse holders have a 50 amp pos. 50 amp neg. to the battery. Hope this helps.
PS The converter(non-univolt) that was here was so scary, I never tried it. No fuses, just direct connected. No battery wires. I cut the wires and dumped it at a yard sale, along with the old water pump.

OK, a promise is a promise. Here are photos of the PD converter/charger in all three of my rigs.

First the 71 Caravel. Messy instal, as it is under the bed and very little room. I used a blade type fuse holder that I had on hand. I used the original shunt so the original ammeter would work as it had when built. I took the shunt from the Univolt box, and tossed the fuse block and Univolt.

The next photos are from my 74 Argosy. I purchased a new blade type fuse block and added two new circuits, one for the furnace and water heater, the second for the water pump. That reduced the load on the original circuits and made both the furnace and water pump have a higher voltage and both run better. Click image for larger version

The third set is from my 75 22' Argosy. I cut the first two inches off the original Univolt, which had the fuses in it and used that over. I am not sure the time and trouble was worth it, a new blade type fuse panel would have been better, but I wanted to try it out. The black block under the original box is a ground block I had and found convenient for the negative wires.
