When my AI was new I experimented by flicking off ALL the breakers under the rear sofa in an attempt to get around the parasitic draws and left it plugged into shore power. Battery was dead of course after a few days (I was really dumb then) and the Kenwood had lost all its settings.

Oh, I just found out today, by trial and error, that the tank heaters are a possible parasitic draw, too, though most of us won't have to worry about that one. I had the main disconnect switched off, and the Tripplite also switched off, and accidentally bumped the tank heater switch while transferring some gear. Sure enough, the switch lit up. I am sure glad for the lighted switch, else I might not have noticed it accidentally switched on! I wonder if that's why the tank heater switch is the only switch that lights up?

OK Bikerbill -- how did you get a set of wiring diagrams from Airstream? I thought they protected them like the crown jewels for some reason.

I asked politely as my conversations were knowledgable enough for them to be comfortable with me to send the file. I sort of did promise not to share them, but nothing was said about me not looking and answering questions though.

Am I incorrect if believing that the electric water heater element due to the size of it's load can never run on the batteries and, like the a/c, the microwave and the coffee pot, can only run on shore power or (in a very inefficient use of propane) off of the generator?

The A/C or the microwave or the coffee pot can run either on shore power or the generator but not all at the same time and none of them will run on battery power. The electric water heater will however run on battery power. Whether you are on shore power or running the generator you only have a 30 amp system and any two of those devices would overload the system. To prevent that the power management system will automatically shut down the device that uses the most power first and if necessary the next down the line and the next until the load is reduced to below 30 amps. If you are connected to shore power and start the generator, the system will drop the shore power and switch to the generator so you still only have 30 amps available.

joemikeb, the water heater WILL NOT operate on the inverter while on battery power. It is not wired to the inverter, only to Shore Power and/or Generator. The water heater electric element is 1400 watts and the inverter only provides 1000 watts at 115 volts. I am looking at the wiring diagram for my 2014/13. The AC, Electric Water Heater, M-wave, the outlet over the sink and back on the right side by the lounge and outside on the right rear corner operate ONLY on 115 shore power or generator along with the power to the inverter itself.

What do the coffee pot references refer to? I have no coffee pot in mine.

There is a plug located in the overhead shelf above the left end of the "kitchen" counter that is designated as the "Coffee Pot" plug. It is only hot when on shore power or the generator is running. It is intended for high wattage devices, such as a coffee pot or perhaps an electric skillet or other high amperage device.

Hidden Coffee Maker Outlet and Aisle Light Wiring

On my 2013 there was also a 120V AC coffee maker outlet buried behind the panel in overhead cabinet right above the sink. See first photo below. I think this is a violation of any good wiring practice to enclose a connection behind a hidden panel.

I changed it to a duplex receptacle and remounted it on outside of panel so I can use this outlet with slow cooker in sink. See second photo below.

I also found wiring for another 12V DC aisle light next to the propane alarm on floor right behind the galley. See yellow connectors in third photo below. I got an extra aisle light from Airstream dealer and installed it -- works great for added night lighting next to bathroom. See fourth photo below.

Airstream apparently hasn't changed the wiring design for things they eliminated in production. That saves them from having to update their precious wiring diagrams.

Out of curiosity I just went out and opened up that panel above the sink in my 2013 lounge AI and found only wiring for the 12V kitchen cabinet counter lights and the pump switch. I looked in the similar panel in the cabinet over the range and found the wiring for the "Coffee Pot" outlet and some more 12V wires but no sign of another 110V outlet or way to install one without cutting the cable and splicing it in.

I am beginning to think the reason the wiring diagrams are so hard to come by is much of the wiring is ad hoc and can vary from unit to unit.

Mine has the wiring behind the panel where Boxter mounted his outlet in photo #2.

Good to hear about the extra aisle lite wiring under the streetside seat. Will have to check mine. Bet the lite is pricey tho. Paid ~$60 for one of the reading lites over the lounge.

I checked my records. It was only $16 last October when I got it from dealer. See photo below of what it looked like before I installed it, chrome outer ring not in photo. I think it was P/N 522377, it is the same light used in the side step foot well. See attached page from Airstream Interstate Part Book.

Hope this helps,

I'm really surprised that Airstream quit putting a courtesy light there. My 2012 has a light there, although it is under the LPG detector rather than over it.
