Converter replacement

Not all converters are the same type so photo or a description would be nice to see.

:h

Mine is "deck mounted" and this is what it looks like:

Planning on taking the new converter and wiring the positive from the battery to the converter post along with the wire from the other side of the old converter, hopefully this solves my problems without shorting anything out.

Talk with Randy at Best Converter. He will help you sort it out.

My Magnateck was getting "weak" according to my motorhome dealer mechanic, and he reccomended a Parallax 55 Amp replacement. $207 on the 'net, got it in a few days and installed it without any problems.
I was amazed at the "evolution" of these things..,.the old one was huge and very heavy, The new one...small and featherweight. Instead of using screws to hold it down, I used a velcro strip. It is that light. Works just fine.

g'luck with yours....

This dinosaur thing?



You might be better to just replace with a new panel.

Do you have a 120v panel? Most now are a combo unit like this surface mount from Progressive Dynamics:

As smkettner credited, I think www.bestconverter.com will be your most advantageous call. Should be a relatively simple swap-out.

Thanks, went and looked in the RV, says its a Newmark product. DCV 30 R-A-C

Guess that is what the answer I was looking for, that it IS safe to connect the battery lead along with the one listed 'converter 12v' together on the new converter + post.

Sounds like you have a parallax 6300. It uses the battery as a filter for some items so there are two supply wires with one going to the panel and the other to the battery. These end up getting connected together as one with a modern converter that does not need a filter.

Here is a link with pictures
This is a 7300 tutorial with additional instructions at the bottom for the 6300.

I thought it would be a simple swap out until I looked at the new diagram. Mine seems to run the battery wiring into the converter while the new ones seem to just run two wires to the DC panel. Was wondering if I should place the + from the battery into the converter + port along with the wire that now runs out from the old converter labeled "converter 12V" ?

Remove just the converter part (4 screws if it is a Magnatek) and wire an inverter/charger into your existing circuits. I just finished the job, and I'm happy with the results - batteries last longer and charge quicker. (I started a thread here), Don't make the same bone-headed mistakes I did :).

If you don't want to go with the inverter/charger plan of attack, I recommend replacing the unit with a Progressive Dynamics unit, which is a smarter charger, but still a converter. Many threads on this topic, including tutorials, etc.

The first step is determine your model number and proceed from there. There are dozens of youtube videos on the subject.
