With every post, this makes more sense!

And yes, if anyone else has the 2014 Magnum inverter, can you please confirm or deny that it only has an ON/OFF setting. I don't see any other stand-by, or charge only, or any way else to set it.

Gracias.

Wow! Thanks so much everyone. I have a lot of revisions to make to the diagram. I better read up on the major disconnect switches and the relationship among the alternator, chassis battery and house battery (BIM). I assumed the batteries were never used in conjunction with one another. And some of the subtle relationships like the house batteries not having enough juice for the charge controller to work really do need to go on the diagram. (I'll certainly forget it by the time it's an issue for me several months down the pike.)

Indeed, Weirdstuff, please wait for the revised diagram. I'm very happy you like the idea though. I can see that I certainly will need it!

Reading these threads, I am always so grateful our older system seems much simpler.

We have a "use/store" button for the battery by the cargo door entrance. This must be the invertor.

We press "use" from the time we plug in before a trip until we are returned home. This allows the battery to charge, frig, furnace and lights inside to run.

If we don't press "use", the battery doesn't charge even when we're driving, interior lights don't work and the frig and furnace won't power on. (Furnace is lpg, frig runs off lpg or electricity) It's as simple as that.

Our systems indicators are lights, shades of green down to red, none of these % that drive everyone wild.

Simple is good for us.

"Thermostat is 12vDC as noted above, and I think— but I'm not sure— that the furnace fan motor is 120vAC same as the fan motor on the air conditioner, else a single switch on the thermostat panel couldn't control both."

The Atwood 7916-II furnace in my 2010 runs on 12VDC; blower motor included.

All these numbers, AC vs DC and technological terms make my eyes cross.

Magnum has Off and Invert Position on control panel along with a menu button. Automatically charges when plugged in to shore power.

Does anyone happen to know if the solar battery charger keeps the chassis battery charged or just the house batteries?

Thanks for confirmation. Had wondered if I was just missing something.

I am under the impression that the solar panel only charges the house batteries.

A second try at the diagram

Thanks again for all the comments, especially 73shark and Protagonist, and to Weirdstuff for constant sanity checks. I'm beginning to "get it," I think.

I have incorporated almost everything that was said, although I left out chassis battery functions (awning and step). I'm wondering if I have the BIM wired correctly. The double ended arrows signify power production from the battery in one direction and charging through the alternator in the other. I suspect (hope!) there is also a direct path from the alternator charging circuit to the chassis battery.

A few questions remain: first, did I get the list of switched 12V devices right that are cut off by the master switch? 73shark, does the water heater really run on the 110 high amp buss? Is it dual fuel, or why would there be a spark igniter as you mentioned later?

Maggie's got a great point! This complexity has apparently bitten just about everyone who's bought an AI lately, from the reports here. Which reminds me: please don't disseminate this until we've at least settled the issues that have arisen here! I am not responsible for actions taken by anyone because of errors here. I don't even own an AI! ;>)

But if I get one, I sure will understand the electrical system better thanks to you all.

The water heater operates on either 110 volts AC or propane. As to the electronic ignition, I'm not sure if it's powered by the AC bus or the DC bus.

You will probably have to make one of these charts for just about every model year as Airstream seems to change the way things operate or are connected. But you are off to a good start.

Battery Isolation Manager

Anything that charges the Coach/House battery can also keep the Chassis/Sprinter battery charged via the Battery Isolation Manager (BIM). The BIM ties the two battery systems together via a large relay controlled by an electronic module. The logic of the electronics that control the relay are detailed in attached manual. This is for the Precision Circuits Inc. BIM 00-10028 (160amp) that is in my 2013 Interstate, yours maybe different.

Third try at the diagram

Sorry. I meant to include the diagram last time, but I'm not familiar with this interface yet. It's just as well. Mike's BIM documentation was very informative and I redrew some of the diagram for that. Although the heater igniters' power source is still unknown, I think I've incorporated the rest of the comments you've all contributed.

I'm sure 73shark's right that the diagram would have to be modified for each AI year, but I think this is a good start. I'd appreciate it if I could have a pointer to the Yahoo group's diagram. (My Yahoo credentials are being rejected now, and I'm not a member of the right forum over there. Plus, how would I find it!?)

Thanks again for all the help. Mistakes and omissions are still solicited.

The diagram, really.

Aha. I remember how to do it now. I was using "Add Video" instead of attaching.

Nice chart David, thanks for putting forth the effort. :-)
