The problem becomes evident when it gets dark and I turn on a couple of lights. They pull enough power away from the heater to slow the blowere and thus drop the sail switch, so no heat. At bedtime, lights go off, heater on, warm time.

I turned off ALL 12v stuff in the camper. Fridge, every light, water pump, whatever could be on. When I did this I got 16.45v at the blue and white wire on the converter.
16.45V alone is the reason to replace the converter.

Still wondering if this could be a ground issue and maybe I don't need a new converter.

I cannot find any fuses on the unit besides the bladed 12v fuses for various circuits and the 120v breakers. Remain hopeful I'll find one after moving a few things to get to the back of the power converter unit and find it is blown.

Okay. I am following the very simple diagnostic there BFL13, and am seeing my converter is bad. Darn.

The two 30a fuses will be on the fuse panel (front upper left on mine), not on the unit, off by themselves, not part of the collection of 12v circuit fuses. Replace both if only one is blown.

Sorry again, that's a series 6300, model 6345 specifically. The 1997 is a different unit than this. This one is a 1992.
Whichever it is, the 6xxx models are similar. You can use the above links to find yours and that troubleshooting step by step will also apply to yours pretty much.
To get by in the meantime, I agree with the others, just use any battery charger you can grab and get your battery back up to speed until later on you can solve the converter problem
(Replacement options --stay away from the 7300 upgrade and the Ultra/WFCO upgrade--choose the PowerMax or the PD upgrade instead for a better converter for the same or less money)

Go to Magnetek and it opens to a list of converters--go down to the 6500 section and check the links to see if anything there helps.
the 6300 section has the link to "diagnostic" which might also help.

ISTR there is a relay that can be stuck which cuts off the battery charger, and ISTR you can bang on it to get it working again, but Not sure. some folks here know how to troubleshoot those 6300s. I have a 7300, so no help there.
I'll see if they still have a 6300 trouble shooting guide posted.
