I’ve assembled my K8086 and as soon as I plug the 12V the relay is triggered, even without the phone line attached. Then when the phone line ring nothing more happen with the relay.
I’ve checked my assembling for reversed polarity components and everything is good and according to instructions.
Also, when I connect the phone line alone or with the 12V the LED lit a little bit, then it’s brighter when the phone line ring.
Please help me find the problem, I really need this device to work.
