Hi. I cant get the macpac to start my mini. The power is there. If I press the power button on the mini it boots so i know the P2140 is working. What i noticed is that the y cable on the carnetix seems to be @ constant power 3.6v as opposed to the isense cable from the macpac which appears to pulse a 3.6v for a very quick second. Any ideas? Am I doing something wrong?
