HI Pylon,
tks for answer and tks to all.
What i mean is "pin compatible for numbers" of course.
Pylon told not for the D13 , what that mean?
I use this pin D13 and D12 to test a contact and it is going to ground. is it the problem?
i think there a problem on the supply, near CC at this time over 9v on the main supply (12v normaly).
many thanks for help.
