My theory on what happened here is that while in for service at Prevost Ft. Worth a couple of weeks ago they either switched the transfer switch to off or otherwise tripped it. In any event it was left in the off position and I didn't know it. This allowed the coach to drain the batteries as it's only source of power. Upon Gary's direction, I then checked and switched the transfer switch back to the on position. I believe that this didn't immediately correct the problem due to a "lazy" or weak relay as described by Paul above. But by firing up the generator, unplugging shore power, then plugging shore power back in, this caused the relay to engage and allow everything to start charging again properly.

Paul, I am going to search that post down and have Liberty send me a couple of relays, but my experience is like Hector's, these problems tend to reoccur at the worst possible time. Thanks for that post.

Gordon, I don't know about a voltage level cutoff for my Liberty, but it started charging right away once the relay engaged.

Just another learning experience..............Man am I glad for POG and for all of you who contribute, including the guys that sent emails directly to me. Thank You.
