2016 25' Rear Twin Flying Cloud
Intermittent, mostly not working 12v
to roof vents, Dometic A/C control. Same (listed) circuit powers bathroom ceiling LEDs OK. (It all worked the last time we prepped and hitched for an outing, did not work when we arrived at camp. Mysteriously decided to work when we got home and unhitched, then stopped working. Does not matter if battery only, on shorepower, with or without solar... that's all well before the DC dist panel.
Yes - 12v
good through all fuses at AC/DC distribution panel to all other circuits, lighting, etc. Bummer as this deprives use of any/all ventilation, heating.
Have full detailed schematic diagrams sent from Airstream. Schematic nor other drawings are specific to exact wire routing, junction/splice locations.
According to schematic the same circuit powers the working bath light as the Fantastic vents and Dometic A/C, heater, furnace system.
Using a "fox and hound" wire tracing signal generator and sniffer have traced and verified the wiring to the bath LED (open wire at fuse panel, apply signal to circuit wire, sniff for applied audio signal...)
Uncertain as-yet where the wire to/from the bath light meets the rest of the circuit. I suspect, hope, this may be accessible upon lifting the cover off the A/C unit when I can get on the roof and I'll find a bad splice to fix.
Has anyone had any similar experience identifying such wire routing within a unit, without doing a restore or ripping off panels, etc. ??
