The fan is on (I think) at least it makes all the same noises that it makes when on shore power.* And yes, it is TIME TO CHANGE MY HOUSE BATTERIES.* I charge them up to ~14.3 (not sure as I'm typing this while in the car driving to the marina - The admiral is driving so don't worry).* They almost immediately srop to 12.6 - 12.8.
I haven't checked the voltage AT the fridge - I'd have to pull it out to get at it, that's next I guess.
I'm thinking it's the batteries dying
* I've known they needed to be replaced for some time now but I want to relocate them and wanted to so the whole job at one time.
