The kick back coil has no diode and its resistance is 4.5 ohms.
The broken D-16 has been replaced earlier.
I removed Q5 and measured it. It was broken (zero resistance in all directions). (By the way, it was very difficult to desolder it because there are three legs and for some reason they have been made very short during factory soldering. This fact made it difficult to desolder one leg at a time, even while using a solder sucker).
I have put a new Q5 (TIP-36C, which I tested first) in place and now everything seems to work!
I have been playing a few games and the kick back coil has been activated several times without any problems. Hopefully, it stays this way. I wonder though, why Q5 broke in the first place.
Thanks for the advice and guidance!
Finally, Swords of Fury is such an underrated game with great music!IMG_20191020_153905 (resized).jpg
