I have sent you an email and left a voicemail with suggestions that will hopefully improve the results you are getting.
Let us know the scope you are using, the scope setup, and the MMY, Engine that you are connecting to. This video might help:
Assuming the COP paddle and lead are not damaged it should give you a good signal as long as there is a signal to get. Unlike the other two COP Probes, the yellow paddle is not insulated and has a large surface, ideal for capturing a signal.
But some systems are so well electrically insulated there is not a lot to capture. To capture secondary signals from these systems you can use the COP HT Extension Cables with the clamp from the AES Universal Secondary kit.
