So did you figure the issue out?

Actually, no. I though I had something with the resistor to ground suggestion, then Alan pointed out that there is already a large resistance in the relay outputs to ground. SuperBK's suggestion is a good one, but programming is not our strength this season, so I don't want to ask the programmers to add any complexity at all. I wrote an Arduino program that uses the analog inputs, and a while loop for greater than ... I'll try that. It should be able to detect the very low voltage we are reading. Otherwise, we'll just run a decorative program. Thanks, though!

(SuperBK is a recent acquaintance...and will be at the NC Regional with us on Thursday...perhaps I'll monopolize some more of his time!)
