I've had similar experiences with my 2012. I even took it into an authorized service center to have it diagnosed. No problems found. Once I re-installed it the original issue was gone. The technician suggested that the "electronics got confused" much like your case. BTW, you can force a factory reset by pressing 3 - specific buttons simultaneously on the SCP. Let me know if you want the specifics ... I just need to look up my notes in the manual.
The reason your settings were still present is due to the SCP because it stores the configuration even when power is removed (atleast that's my experience).
My fans run 24/7. Do yours? Supposedly, the internal temperature must drop below 113 degrees once the fans activate. Apparently, the charger would have to be almost frozen for that to occur because they never shut off durin g the previous winter. I purchased a small Schmacher 3-stage deep cycle charger to allow me to disconnect shore power while parked in our garage.
I assume you have the new Xanbus AGS. Works great hey?! MUCH better than that old POS.
