Univolt To Power Max Boondock 45amp/New Converter

I read similar threads and feel I am close to being able to change out the old Univolt 1973 vintage with internal fuses.

I bought a PM4B-45 from Best converter along with a Fuse Block with 9 positions. The pictures show these and Univolt I have. The Univolt is clearly marked which is good.

As I see my task so far:

First, I need to disconnect the hard wired line into Univolt and use that and install a Receptical, since the Power Max has a plug. I will use a 20 amp GFI I have laying around since the Romex is 12 gauge and located in the rear bath area, if that is ok.

Is there anything I need to know about mounting it to the inner skin, on a rib. 5/8” Pan head screws Ok?

Next, I will mount the fuse block I bought and use 4 20 amp blade fuse for the 4 lines currently on the Univolt in the upper left circuits 1 through 4 in picture.

If I understand correctly the Univolt “power on”, gray wire is not used in the new set up? Nor the amp meter black / amp meter red won’t be used in the new set up?

CAN SOMEONE HELP ME WITH THIS? I need to get some kind of addition fuse holder or inline fuse to take care of the 40amp Black line label car battery and 50 amp for the red line below it labeled Trailer battery and the black labeled trailer battery below it that is not fused. Any examples you could show me would be great

Could someone tell me what do I do with the black line from the trailer battery

Please anything else I am not addressing let me know.

Double thank you in Advance.

Tony S

I maybe answer my own question via another post I read. Is this inline fuse what I should be buying.

Hope not to be misusing someone photo. If I am sorry.

Thanks

Tony

This is what I did with mine, that way you get the ammeter ( such as it is). So now I have the best of old and new. The fuse at the top of the box is a 50 amp on the neg line from the battery that was mounted on the side of the trailer.Hope this is a help.....Phil.

Phil,

That is pretty sharp. I had seen the photo before in my research and was looking for it again, thanks. So you bundled up the old parts with the new in a metal case, nice. Do you close it up in use?

Tony

Sorry, I didn't see your question until today. The box is an old Makita drill box ( before plastic ). You can see the open lid at the bottom of the picture. This is what it looks like when shut. It's screwed to the furnace duct at the bottom and bolted to a bracket riveted to the bed rail at the top.....Phil.

Thanks phil. I ran around my shops looking for such a box including drill carrying case that I never use. All mine was molded plastic. I do have one possible box that just needs a clasp

I did go out, however and bought 3 inline fuse holders just to have an option on hand when a friend comes over to give me his 2 cents and help me out.

Thanks

Tony
