Ok, I know I have another Williams fire post, but it won't let me adjust the title.
Long story short.
Q22 was shorted and the bell and knocker wouldn't work.
Changed the transistor and replaced the diode on the fire bell coil.
Now when I connect the bell coil (it has a plug) seems like switches and other coils fire each other with no rhyme or reason during coil tests and game play(there probably is one, I just don't know it).
For example, the bell rings on about 25% of switches. So if I press the flipper buttons, it rings, score some points, it rings.
Same goes for the ramps going up and down (although with other switches, not the flippers)
Even as you rack up points it causes the coils to kick the balls into the shooter lane and things to happen.
Unplug the bell coil? All goes back to normal.
Not sure where to look.
