For those of you that have been following this thread, here is the latest.
Just got the buggy back from FL. They wound up having about 9 clock hours into it and the final fix was to remove the connector at the message center end and then plug it back in. Suspect that when the batteries were checked and then reconnected, something "latched" up the VIM ( Freightliner Computer) and removing the plug allowed it to reset. Just speculation though, don't think we will ever know for sure and i'm not of the frame of mind to try to repeat the problem. They did find the breaker on the frame rail but they said it was a thermal reset type that will reset itself after cool down. Incidentally, there were three breakers down there. Location was passenger side, framerail,outward, general area of battery slides. Not the fix I would like but, hey, we are rolling again. All covered under FL warrenty.
