Well guys, another 5 hours out there today. I tested the voltage at all points and it was pretty steady at between 47.6 and 50.6V. The one thing I noticed is that when I plug the phone in at the far end and watch the voltage it stays at about 47.6V and after about 10 seconds drops to 3.3V and after about another 10 or 15 seconds it went back up to 47.6V. As a test I watched the voltage on another port of the Definity and shorted out the pins on the 66 block and lo and behold the same thing. It seems like it is shorting out somewhere but the voltage holds steady at 47.6V until I plug the phone in..I have not tried to bypass the Circa but will tomorrow..btw skip555, which Circa modules did you end up using? I will call Circa on Monday...
