I understand the 6300 manual states that it needs a battery to regulate voltage. Are you testing this part of the instructions?
The “Owners Operation/Warranty Manual” I have is a single 8.5x11 sheet, double side printed, and folded in half. More of a flyer than a manual ;) But nothing stating a battery is required for 12V operation or regulation off shore power.
In any event, we are not disconnecting the battery on purpose. It generally happens when someone forgets to turn the battery disconnect back ON after the RV has been sitting for a few days. I just happened to notice it when things weren't working correctly, and measured the voltage to see if was a low/high voltage issue, which it was. I then tested and noted it was only with the battery disconnect switch set to OFF.

you are definitely flirting with 12VDC appliance failures operating them on 16.5VDC...
Sounds like you may have blown a couple of items already from your post...
Luckily, haven’t blown anything yet. When I unplug from shore power and run off the battery directly, or turn the battery disconnect back on, everything works normally. However, its only a matter of time before someone leaves the RV inadvertently plugged into shore power with the battery disconnect off for some length of time. I’d like to avoid that :) Hence my troubleshooting questions here.
Until I upgrade the converter, add solar, etc, Ill just put a warning flag on the shore power electrical cable to verify the battery disconnect switch is turned ON prior to connecting to shore power. And another label on the battery disconnect switch.
Can I safely use the PD4645 converter as a real converter, to convert 120C to regulated 12V without a battery connected? I’ll download the manual and read up.
