Converter fan running... batteries fried... batteries replaced... fan still running!
I know this is an oldie but a goodie, but I'm stumped. We switched out the batteries today in our 2016 Flying Cloud 25'. They were due and had crapped out while in storage. Prior to the switch the converter fan was running constantly, which we realized was a symptom of the battery problem.
For about 20 minutes after we installed the new batteries, the fan was off, and we left the run errands. Since we returned, which was around an hour and half ago, the fan is on and hasn't cut off. We are plugged into 50 amp shore power and the batteries are reading 13.6. Is it paranoia, or is there still an issue?
