Hi, One of my Beloved cameras developed Aperture block failure and to fix I need to replace a solenoid. Read-up Pentax K50 aperture block failure and there are several youtube videos too (for people interested). I removed the horse shoe magnet to check it out. The picture shows the donor solenoid from a dead camera. I haven't done soldering on such tiny part, so question: Many want to remove the solder on the solenoid from the wires and solder to the wires on the camera that needs a fix. But I am worried that the plastic above the coil might get damaged if I touch it more. So can I cut the wires and join the wires on the camera that I want to fix? One person suggested to use shrink tube, again I don't have enough space inside the camera to shrink the tube with a heat gun. Can I just use good old electrical tape? Any other alternative?
