Simple Univolt replacement

I know there is a ton of stuff about Univolt replacement here, but I'm going to ask a few, simple questions. I have done some electrical work on buildings and have some idea of how domestic electrical stuff goes together. Enough knowledge just to get into trouble? Perhaps. Anyway, here goes:

Can I just take out my old beige 1964 Univolt and wire in a new converter, like this one
9200 9245 Amp Progressive Dynamics Inteli-Power Converter
replace the circuit breakers
and replace the 12V block with the fuses, all of this by following instructions, removing wires from the old device and connecting to the corresponding terminal on the new device?

Thanks

I just pulled the fuse block off the old converter and re-mounted it.

The only loss was the 'converter-on' indicator light on the panel which I didn't bother with.

A new fuse block using modern ATO fuses might be a good idea, though. Those old ones tend to corrode over a few decades and that can create significant voltage drops.

Thanks Bryanl. It seems that I should be able to replace like for like, but then many things that seem simple aren't. I don't have anything like a converter on light, the only light is a bulb in a switch box that goes on if the polarity is reversed.

That is to say, like for like: remove the univolt and pop in a new converter, replace the circuit breakers, maybe just using the existing box.. heck, I can do that today, and they'd be new breakers. The weird thing is the 12v stuff. At least our trailer is relatively simple.

I changed out the old converter in my 65 with a PD9245. I used the original 12 volt fuse block and breakers. It was a very simple job. Still working great over a year later.

tkasten, that is what I'm looking to do. Does your PD9245 charge the battery when you're hooked to shore power?

Yes battery is charged when hooked up to power. In fact the PD9245 is a smart 3 stage charger that does a great job. I have installed 3 lifeline batteries under the side couch over the axle and they are very happy being charged by the new converter.

Thanks. so you changed the location of your batteries? I'd like to change ours, but want to find out more about venting etc. I imagine with a larger enough conductor, they could go anywhere that made sense, to carry the weight.
