I wanted to add to the battery comments. Many many of the times things were not quite working right ended up being due to the battery not being charged or good.
As Al mentioned a voltmeter does not give a state of health on the battery. In Atlanta we found out that we only had brought 4 solid batteries out of the 8 we had shipped. The only way we found out was through a load tester that 1114 gratiously let us borrow. Needless to say the first thing we bought when we got home was the exact same battery tester as 1114.
I'll list it here: its an Midtronics SCP-100 SCP 6/12
