I think you ought to drag that thing out of storage, and meet up with us and some other folks in the Arizona desert in early January.

Would love to!  We are grounded until wife gets a new heart.  Maybe next year.

Nothing serious you understand. 

Yikes! Hope all comes out well.  I had quadruple open heart surgery four years ago and I'm really impressed with how the medical field has come along. It's really amazing what they can do for you.

Yeah, that's certainly a good reason not to come. We completely understand. Our prayers and very best wishes are with all of you. On a positive note, a friend/retired DEA agent I know got a total heart transplant last year and it's truly remarkable how well he's doing. It's hard to believe he's the same guy. He takes a bunch of pills each day, but he could probably walk us all under the table. We'll see you next year. KOFA's not going anywhere.

Brad: without going back to look at your charger panel (but I think you have the mini) the ME-RC and ME-ARC have the capability to set the max AC current draw. I rarely take an external generator anymore, but can easily charge the coach on a 1000w generator. I simply set the panel to my shore supply and the Magnum manages the max draw through the inverter and charger together. If yours doesn't do that and you are hanging at friends houses, etc., with 15A service, you might consider upgrading the panel.
Now to go read up on that little panel...

(Later)....  Been reading. You do have control of max load on that panel..  Setup 01:Shore. Just matchnthe breaker and the load preset. Just be aware that calculation does not include fridge on AC, MW, or HVAC

Still the question is why you get a comm error? That panel is powered from the Magnum itself. Is there anything plugged in to the StackPort (Red) on the inverter?

PS- Just read your last comments.. Yikes.. hope everything turns out good. I have a friend that just went through the same and he's already back on his feet and starting to be the big ol' PITA he's always been :)
He's even talking about Quartzsite again :).

I think the remote is actually plugged into the Stackport, but I'll have to look again.  I was thinking of trying to unplug it there.  That is super info on being able to control the max load!  Thank you.  I'm anxious to try it.

Thank you all for the kind words, prayers and well wishes for Dory!  Your experiences are good news, as it is consistent with what the hospital is saying. 

She is currently in the final stages of recovery from having an LVAD (left ventricular assist device) installed which involved open heart surgery to install the pump into the left ventricle and aorta, powered by a control system and batteries from the outside (her and my world revolves around batteries..........:) ).  She is on the transplant list with a pretty high priority because the LVAD is considered life support.   We get the MH out to go to local state parks, but we are pretty much restricted to 2 hours from home, waiting for the call.  Ironically, with all the back up systems on the MH (inverter, generator) she is safer in the MH than at home :)

Careful.. you might let all the smoke out. The panel should be plugged into the remote (Blue on the 2012) port only. does the inverter turn itself off when you kill the house batteries? If so you probably have a remote sense plugged into the stack port somewhere. magnum makes some cool little widgets for controlling the box, like a simple tiny switch to turn it on or off from bed, or another that you simply remove 12v and it shuts the inverter off. I installed that one, but think I'll install a timer that I can turn off the system for those who seem to think the TV is a nightlight when boondocking.  >:(

Both switches on my coach are off but the light on my OBDll reader is lit.  I doubt that's a big draw, but I wonder what else might be drawing my chassis battery down.  I don't have an inverter.

On Winnebago units the entry steps operate off the chassis bank, I think I remember reading about reports of something going wrong with steps that causes a constant current draw.

I remember that on the step too, something got stuck and killed the battery.  I just don't remember what it was posted under

Multiple things bypass the chassis battery disconnect switch, e.g. the electric step motor, the LP and CO gas detectors, and probably the ECM (engine computer) memory. These fall into the category of safety devices or functions necessary to restore operation in the future.

John and Brad, if you find that post, please repost.  It's likely more than a Winnebago issue.  The steps on our Pace Arrow failed to retract twice when we started out.  Fortunately the DW caught it.  The on-off switch seems to have a mind of its own.

On Winnebago units, the step extension and retraction is initiated by a magnetic reed switch on the entry door, the steps stop retracting or extending when the monitored step motor current exceeds a predetermined value.
