Just noticed what the solenoid that's used in the 'recall' draws. It's a continual 0.72amps!!!!!

I'm in the middle of a Grand Tour solar/ lithium/ Magnum upgrade and when I went to remove the old inverter cables, I noticed that the solenoid in question was HOT....... Like over 125 deg. !!!!!

I measured the amp draw just before removing the device, as it is no longer needed when I do a full upgrade.

It would have been simple to use a latching solenoid that draws NOTHING after the contacts have been engaged. Just another cheap, essentially worthless 'feel good' upgrade!!!!!!

So without the solenoid the house batteries could be drained to a 50% charge state in about two days of non-use. With the solenoid, they would be drained in five days of non-use. I am underwhelmed.

I still can't fathom why the manual marine disconnect switch is not the preferred method of isolating the batteries or the inverter. I use them on every installation that I do and they have a ZERO amp draw.

Lew - I agree with you. It was obviously a typical corporate money driven decision to use a cheap solenoid. Form the pictures of that solenoid that I've seen it looks like the cheapest one you can buy.

I finally found what was causing the the "Fault! No Comm" message from the magnum inverter. In my case, the positive battery cable to the inverter was not fully connected. The nut on the terminal only had about three turns on it, so the cable was loose. As soon as the the nut was torqued down, the problem vanished. For what it's worth.

Sounds familiar. The only real problem I've had with my Interstate was caused by a loose connection of a large terminal lug on the Battery Isolation Manager (BIM). My tank monitor panel was intermittently not working. I was able to isolate the problem with a phone call to an electrician at my dealer, Colonial Airstream in NJ.

I'm sure in the rush of production an occasional connector doesn't get tightened fully. My lesson learned was to check connections first thing if you are having any strange behavior in your systems.

Having nearly had a fire with loose battery terminals on my boat house battery, that is the first thing I check now. I grab all the cables and tug left and right. No movement should be there. I also test for elevated temps by touching the terminals. On my boat, insulation around the terminals was completely melted!

Just had the same issue with my brand new 2016 interstate. The 80 amp solenoid before the inverter went out and needed to be replaced, literally the day after I took delivery. Late post to the topic here, but wanted to add to the knowledge base.

I had two selenoids replaced until I had it disconnected. No problems now

So you removed the solenoid altogether? Mine was replaced with a 200amp solenoid with the comment that "they always make the solenoid too small before the Magnum inverter"

My opinion is the selenoid adds very little to increasing battery life but is a weak link for something to go wrong. I am not mechanical and don't want to get involved in working on anything electrical.
