I have not done any tests Lee.
I figured I would ask here first to see if I have a problem. If the draw seems excessive, I'll check and see if I can figure out where the power is going.
I know there are some 12V things that draw power with the Coach Power switch is On (dash radio/clock, Inverter (if left on), maybe toilet circuit board) but I can't think of much else.
Possibly the Inverter was providing 120V to something too. I have it set to "search-sense" for any over 20W load (the lowest setting). That may be providing 120V (memory) power to my TVs and my walkie-talkie charger. I don't think I had the HWH system in "auto", but if I did, I bet the aux air compressor would pull some amps.
