When connected to the Buffalo II, voltage drops to 0.009V (measured at Buffalo II inputs). It worked fine yesterday. What could be the trouble?

Yes, I tested with another Placid and Buffalo II board. The fault is on the Buffalo II board. Originally Posted by: Russ White Sounds like a short - could be a dead regulator. OK. Any way to tell which? These are the 8-pin parts labelled 176333/1763? I think I could probably replace one if need be. I have a spare Placid available if that will be useful for diagnosis.
