No DC in 1999 Coleman Bayside
When plugged in, AC works fine throughout. It is a 1999 Coleman Bayside. I had this problem once before -- what concerns me is it "self resolved" and now it has occurred again. There was a post by so...

Thanks for all the replies - here is an update.
The converter model is a Magnetek 6700 series, model 6720
I have two 12V batteries connected in parallel.
All fuses are good - including the inline one near the battery.
All 12v outputs work when connected to my Yamaha 2000 generator (AC).
When the AC is connected, I measure 12V (+) out of the converter (going to the internal lights, etc. of the trailer)
On DC:
I measured 12.6Vdc in from the battery at the input point to the converter.
When the AC is off/disconnected, and I measure the 12Vdc in, there is 0V dc measured on the output of the converter. So I suspect there is a bad diode or some other circuit board component preventing the 12Vdc to pass through.
More info:
Magnetek has since gone out of business or is no longer available. Parallax makes a compatible model 6730D, which I bought from BestConverter . com (fast shipping and friendly service but NO schematic for Magnetek).
I brought this new converter to my trailer in the mountains (1999 Coleman Bayside) with the intention of replacing the Magnetek... I must have scared it - as now the 12V dc is functioning as expected... so I have a new converter in a box in my trailer... hoping the Magnetek will last the rest of the season so I can do the remove and install at home. I do wish I could locate a full schematic for the Magnetek 6720 as I figure I could locate and replace the failing component (if that is indeed the case - hard to trouble shoot when everything is working again.)
