Okay. After looking at some of the notes here, this is what I know. The "key"was not in so assume disconnect was open. Got it in and it was not really clear which was the "key" was to point. I could point it vertically two ways (small flag up or down) and could not remove it. Had to turn a bit farther counterclockwise to remove. With the small flag up after several days, I made these observations - the little green lite was flashing on every 5 seconds, battery vdc was 13.25 (13.1 with small flag down - I now believe the small flag is the pointer). It now appears the battery in being charged by the charger inside the power center/converter.
And Lenny K, thanks for the link.
