Update: I figure I'd update the latest incarnation of my electrical issue. I went back to the storage unit this morning to bring the Berk home. Its been unplugged for 3 weeks with batteries turned "off" in the battery compartment. It started right up and house batteries indicated partially charged( I just noticed they weren't fully charged). I got it home, plugged it into my house(20amp) and the inverter indicated "ac in" and "bulk". Mysteriously my problem is solved. So, my guess is that the 50amp service at my storage facility is to blame. I'll bring my multimeter with me when I go back to the storage facility to check the plug voltage.

Don't know if I'm right or wrong, but we never turn off the batteries unless we are doing some kind of maintenance. When at home we just plug into a 20amp outlet. Always check the battery water levels once a month. Hope this is the correct procedure. skip

Skip, I'm going to have to check the battery water level. I had to shut the batteries off because I was coming back to dead batteries at my storage facility(even when plugged in). Now my bulk charge light has gone from solid to flashing, which indicates a problem with heat or low voltage. The book says the proper charging format would be solid bulk to solid absorb to solid float. Before long, I'm gonna be an expert at this.

Glad to hear things are working better for you.

Years ago in the 90s I picked up this book. It was updated in 2002 and I recently picked up another. I find it to be a great reference while camping. Its stored permanently in my trailer.

Thanks Scott. I'm getting a clearer picture of what my 12 volt system should do.
This morning, I got up to check the water levels in my coach. The batteries are Lifeline deep cycle "maintainence free" so no way to check the water. The big surprise, the Magnum remote was on solid "float"!!! This leaves me with several questions. Why did the batteries die when plugged in at the storage facility? Why did it initially work when I brought it home(solid "bulk" to flashing "bulk")? And finally, What happened over night to fix the problems so that the batteries are now on "float"? Never did I reset a circuit breaker or replace a fuse. Is my Magnum named "HAL"?
