Question Converter not charging batteries

I am a newbie to rving, but I do know some. I have a 2012 Winnebago Access Preimer 26 qp. My converter is not charging my batteries and blowing my 2 30 amp fuses. I think I'm going to need a new converter, but have no idea what to buy. What could possibly cause the converter to quit working and blowing my fuses? What is in there now from the factory is a Schumacher model RVCDP55, 55 amp. They don't even make this model anymore. One of my questions is, what would be the best upgrade that I could replace it with. Any help would be deeply appreciated, since I'm not that savvy about this sort of thing and I don't won't to invest in something that may not be good, or be taken for a ride at some place.

When you disconnect the converter and have charged batteries does everything seem to work? It would appear you have a short. How did you determine that your converter is bad?
I bought me replacement converter from bestconverter.com. Lot's of help and info on their website.

If the 2, 30 amp fuses are on the converter itself, they are the reversed polarity fuses.

If you just installed the battery and this problem arose, you have the battery wired backwards.

It appears the only thing the conveyer is doing is not charging house batteries & blowing fuses when plugged in. Everything works when batteries are charged up.

Well it won't charge the batteries if the fuses are blown.

Do the fuses blow if you disconnect the batteries?

With the batteries disconnected what is the DC and AC output of your converter?

You may well have a bad converter but you need to check other parts of the circuit as well. It would really suck to replace your converter and have the same problems.

I would pull the converter and start looking it over. With something this drastic it's likely you will be able to smell that something burned up. Hopefully you know how to use a meter? If you don't smell anything cooked than plug it in with the output unhooked. It might not be perfectly stable but it would have an output of 13-15 VDC if it's working.

In a pinch you could just use a cheap charger for your batteries if you keep an eye on the charging process. Of course, if you have hundreds of dollars invested in your house batteries you need to get a shunt/meter and a new converter ASAP.

Good luck
