2012 TAB 320 Electrical Problem

DragonnClaw

I have a 2012 Nucamp TAB and my original Parallax 6730D Converter basically died and they don’t make it anymore. I tried to look for a replacement but no luck. Even finding someone to rewire it has been a nightmare. So, I’m hoping someone here has recommendations and/or has the wiring diagram so I can give to a mechanic to get power back in my teardrop. Thanks in advance.

Welcome to the Forums....

There are a lot of posts about re-wiring or replacing the "WFCO" converters in the Tabs.

Are you the original owner?  Is this original equipment on your trailer? 

Some photos or measurements would be useful, and it sounds like you might already know if the "WFCO" converters or one of the Progressive Dynamics converters would fit.

A lot of owners have tackled this sort of thing, and there are several threads with examples that should help.

I’m not the original owner; more like second or third. It is the original equipment.

Thank you.  Some pictures might be nice, mostly to see if the newer converters will fit.  There are several other threads about replacing various WFCO units, but all are for newer trailers.  We might "think" this would be a straightforward replacement, but...hard to tell.  There is tons of info in various threads that will describe the basics of the electrical wiring from the front "junction box" into your converter, etc.

This is a discussion of a "Progressive" converter install.

This is a broad search of the group for "converter install".  You may have to wade through some threads, but have a look at various photos and diagrams of the various wiring setups owners have worked out.

("Qwant", by the way, is a "de-googled" search engine that actually works!).

This is a search for "converter replacement" with just "Images" selected.  The search results show all the various diagrams pictures in the various threads about converters.  Again, a "qwant" search, which gives me back the results that a Google search used to provide...but no longer does.

I'm kind of surprised that the Parallax 6730D was the original equipment. I have a 2013 and by then Pleasant Valley was using the WFCO converter. But it seems like PV was doing a fair amount of experimenting with parts & suppliers in those first couple of years of production...

Various 6730D replacement searches recommend the PD-4135 as a replacement.
Those searches suggest the 4135 is the same outside dimensions as the 6730D.
From one Convertor Supply Company:


I'm not aware of a yr-2012 typical wiring diagram.  Does your 6730D have any 120V Breaker labels or 12VDC Fuse labels to assign a technician with the installation?  The 6730D appears to be a simple unit with very few breaker & fuse positions.

Attached file has a typical Dutchman 2008 electrical wiring diagram . . . since the 6730D has limited breaker/fuse positions it is possible your nuCamp build is similar.
