Well no sooner had I sent that email when bank 2 started working again. I am suspecting it had to do with the battery test I was doing. I ran the battery all the way down. I guess that's a warning to me not to do too many things at once.Looks like it just needed a bit of a charge internally before it started working again. Weird but at least it's back up and running.
