Understood - and thanks. I pulled the two reverse battery fuses to check and they're both good. Put everything back together and now I'm seeing 13.5 volts on the aux meter. This is good news but still concerning because I don't know the fault cause. I will monitor can keep my fingers crossed.
If all other things in the circuit remained the same when you checked the fuses, Occam's Repair Wizard tells me that the fuses, in particular the contacting surfaces may be to blame.
Mena might also have nailed it, a corroded, dirty, or loose connection may be the culprit.
I would suggest, too, that you purchase a handheld meter to verify electric issues. Some of the metering and monitoring devices in RV's are rather cheap and of lower quality.
