A while ago I purchased a Turnigy ESC prog. card. (the white one) Was able to program the ESC on my RCX 450 with an RCX ESC/BEC. Everything went great.
Today I tried it again and NOTHING, the card lights up and that's it. No blinking anywhere. I am aware that this card isfor"specific" ESC's howeverhow did it
worked two weeks ago andnot now? Polarity is OK, it's being donethrough the ESC slot on the card and then power is applied.

Any help will be appreciated</p>
