Kevin, thank you, I am going to go ahead and order a 9245 and new fuse panel. Any idea what size panel I should order. It might be nice to have a few spare circuits available for future upgrades and expansions.

AWChief. I think you are right about what it is- "an absolute mess". I am not sure when Univolts made the scene, but my idea of a Univolt is a primitive self contained 110 to 12v converter with a transformer, condensers and a fuse panel. Looks like you have a transformer there. There was a time in Airstream history when there were completely separate 110 and 12v systems. I don't know exactly when someone at the factory decided to connect 110 shore power to a converter to charge a 12v battery. Maybe there is some Airstream Mystery Mavin out there that has the date?

It has been more than ten years since my '64 Overlander's original Univolt was replaced, so this is from memory. I believe that it had space for 12 fuses with 9 utilized. My Overlander has nearly every factory option and a number of dealer installed accessories so I don't know what a smaller coach with less demands on the 12-volt system may have had.

The fuse panel in my new setup has 16 circuits with modern automotive "plug" type fuses. It is overkill, even for my Overlander as I am only using 12 of the circuits. I went with the larger panel as I was having a solar system with three AGM batteries installed and knew that I would be adding additional 12-volt circuits over time -- one of my first additions was a 3-way Dometic Refrigerator that allows me to switch to 12-volt when traveling.

Good luck with your project!

Kevin

The 1964 Airstream trailers were the first to be equipped with a standard Univolt. All of the interior lights in the '64 coaches were 12-volt, but the ceiling vent fans, water pump, and furnace blower motor all had transformers between them and the coach's power. Those early Univolts were even more temperamental than those often written about in the 1970 through 1980 coaches. They were extremely heavy, boiled the electrolyte and required that a battery be in the circuit for proper operation. In reality, they were little more than a battery charger that was not kind to the batteries to which it was connected. My coach's original Univolt failed on my first camping trip in 1995 so it was replaced with a Paralax converter . . . and later by an Inverter/Charger when my solar panels were installed.

AWCHIEF, presumeing by now you have completed the replacement of your UNIVOLT in your BAMBI II. I also have a 1964 Bambi II in need of UNIVOLT replacement. If you replaced the UNIVOLT with a 9245 converter, where did you purchase the 9245 and how did you provide both 12 volt and 19 volt outputs so that the vent fans will still work? Can you post and electrical diagram of how you did it in your BAMBI II? Would really appreciate it.

Actually I have not made the replacement as of this time. A couple of higher priorty issues came up. It is still high on the todo list. When I buy the converter I will get it from : BestConverter - Converters, Inverters, Electrical Supplies, Electronics

Sorry can not help with a wiring diagram at this time. I will have to draw one up when I do the swap. The best I can do is the manual copies I sent you in the other thread.

As for the vent fans, I won't swear to this, but I bet that they will operates on 12V just fine, albeit not as fast.

It would be an easy thing to test, even before you make the change. Otherwise, I suppose a step-up transformer would do it, and failing that, new fans.

Thanks for reply, AWCHIEF. May I ask why you have selected the PD9625? I just did a google of "Powermax Boondocker versus PD9245C" and found a post on another RV forum that advises against using PD9245 with AGM batteries as follows:
" If you are looking to upgrade your coach charging system then first thing is to read this Trojan site document: http://www.trojanbattery.com/pdf/TRJ...UsersGuide.pdf.
Please note that Trojan says DO NOT EQUALIZE AGM Batteries. To some degree that limits your converter/charger selection. The Powermax Redneck selected fits that bill for that requirement as well as charging voltage. My PD9200 does not as it's more oriented towards a wet-cell, not a AGM. As you can see, the devil is in the details but with care, one can work though it."

What is you opinion of this equalization issue?

Have not heard about not using the PD9245 with AGM batteries, in fact just the opposite. The manufacturer recommends its use with AGM batteries. It was recommeded to me by several people that use one and have AGM batteries. They are very happy with the combination and have experienced no problems that I am aware of.
Also the folks at BestConverter recommeded its use. We talked in great detail about what I wanted to do, including upgrading to 2 AGM batteries.

AWCHIEF, just for your info I called ADVENTURERV.NET and talked to their technical expert Randy. He tells me that although they sell both the POWERBOOST and PD9200 products they recommend the POWERBOOST converters with AGM batteries for Airstreams. It is $10 more but has a 3 year warranty as opposed to PD9200 products 2 year warranty. It is also their most popular deck mounted converter and they have had not problem returns. Haven't made up my mind which to purchase yet.
Can anyone on this forum give me any advice as to which to purchase for UNIVOLT replacement on 1964 Bambi II??

I was not familiar with Adventurerv.net so checked out their site. Is Powerboost the same thing as the Power Max? I cannot find Powerboost on their web site. My use of the PD9245 is not locked in stone. I am open to any unit that will work for my needs.

My mistake, AWCHIEF, when I wrote the post. Yes the converter I was talking about is the PowerMax.

Jellis00: The PowerMax looks like a good unit and the prices are a bit better than the PDs. As soon as I get this brake issue I am having fixed once and for all the converter swap is going to be the next project. I am going to have to do a bit more research after your post. The PD converter may not be exactly what I need. Keep us up to date on how you swap is going.
