The part that is at the very left of your photo, is the transformer, that may be in a box.

Andy,
It looks almost impossible to remove without taking the entire thing apart and even then I think it might be adhered to to cover in some way as I think it was originally like that because of the heat factor. What if I were to do this? I can leave it assembled and stand it upright in a bucket with the transformer at the bottom. I can then fill the bucket with varnish to the point on it being emerged without getting to the other components. Leave it that way for several days then let it dry out. I wont be able to rotate it, but if it is completely emerged and soaking for a few days maybe it will get there. Ill also let it dry for a few weeks and keep it in the sun so it will evaporate as much as possible. One other question. With varnish being flammable and an inverter getting hot should I be concerned for on down the road when its hooked up?

Your transformer is already potted and encased.

The repotting can only take place with the actual transformer, without any covers or encasing.

Varnish has been used to pot transformers, for as long as varnish has been around.

I don't have any other suggestions for you to try, other than creating a sound barrier.

Andy

Andy,
Thanks again for the help. I just went back into the garage and looked at it again the tan stuff in the picture above almost like stiro-foam is literally glued to the metal box around it. The only way I see to get it off is to chisel at it which probably is not a good idea. Maybe its best to leave it alone if my idea would not work, or buy a new one.

Unless you absolutly must have a "perfect, period correct trailer", there is no future in univolts. The modern three stage chargers are so far superior, that there is no second place. Univolts belong in a museum, or the trash.

See the intellipower mentioned by Aaron in #3. Looks like a good unit. Looks like Andy (inlandrv.com) has the original style univolts at $195. Mine hums quite a lot, so I plan on giving varnishing a try this fall perhaps.

Andy what do you think repot or not?

Andy,
Before trashing it I decided to give it one more shot!!! I took it apart and did the only thing I could which was to start cutting away at the metal since the two were practically bonded. In doing so I think it is damaged. Much of the crystal like material is coming off with the metal, and is lose. Ive stopped for now, but can continue if it is still salvageable. Believe it or not I would rather this work than have to buy another and I'm very curious now. Let me know what you think or does it go in the trash?

Thanks Cody

It looks to me like it has been exposed to a lot of water, and this is never a good thing. If that were mine, I'd toss it at this point - both the inner and outer cases are in bad shape. I think that in theory you can salvage it, but I'd be leery of putting a repaired unit that looked like that back into my trailer.
