I'm starting to see the end of the tunnel of a long shop job of an F-14. The previous owner(s) had stuck a piece of cardboard in the flipper relay (K1) to keep flippers engaged at all times. I blindly replaced the relay thinking it was the relay that was toast. For kicks I measured the old relay for continuity in the coil and it buzzed immediately realizing that there's something else that's broken.
I can't really make out what fires the coil inside the relay. One thing that had me thinking is that I could see that there's a diode for the coil (D2 according to the schematics) but there's a tiny resistor there instead and it's next to the battery. This must be a typo, right? Because the closest diode is D3 just above it.
I only have a cheap scan/reprint of the manual and I'm not sure I have the whole story in mine.
