especially since it seems, from your description, that turning off the use/store switch also removes 12vdc from coach batteries to the inverter.

This only happens after a 30 - 40 minute delay?

So the inverter DC side must be on the load side of your coach disconnect. That's why previously I was wondering what would happen if just the inverter DC ground cable was removed (safely) temporarily for a retest of the situation.........or......leave it as before when you were testing and the ant/cable LED stayed on for 30 minutes before shutting off by itself.......

The loss of power to the Inverter and Ant/Cable shut off at the same time. I am beginning to be convinced that the Ant / Cable wall plate must be on AC circuit with Inverter, but Inverter can be physically cutoff but the Ant/LED is still on; but I suspect no real power boost to the antenna. I bet my TV would lose the antenna signal as soon as inverter turns off regardless of the LED for Ant being on?

try turning on some heavier coach battery loads (fans, lights, water pump etc) with shore disconnected and see if the ant/cable LED stays on......or shuts off much faster.

I have tries this a few times. Of course the Inverter has to be on, but I have run TVs, and outside fridge and it still was about 30 - 40 minutes (maybe 200watts of draw) before shutting off. No change from when just the Ant / LED by itself. If we need to really juice it up, I can additionally turn on my Norcold as it is hot outside and that fridge draws a lot compared to outdoor kitchen fridge?

I did take it all apart last week, but when I learned that it does in fact cutoff with the delay, I thought it was resolved. But Winnebago was wrong when they said it was charge within the Inverter. In hindsight, another test I wish I had ran was to verify what happens on the 12v input to the back of Inverter when the Coach switch was turned On/Off. Magnum Energy was adamant that my Inverter has no ability to hold energy. It has a minimum incoming voltage limit and when it hits that; it immediately shutdown.

So now, I know what it is doing, and I like what it is doing , but AMAZED that no one can say why, or even how it could be possible; not even Winnebago?

You think maybe I should put my drink down for future tests I am about to go nuts , but I am going to find out why one way or the other and I will share what I learn.
