I've been chasing my tail trying to fix a non-functional left flipper on my Sopranos after a diode>transistor failure. First I replaced the diode and transistor. Didn't work. Then, I sent the boards out to be tested and/or repaired. Tech says there's nothing wrong with them. The only thing left to replace is the coil. When I replaced the diode, I just put it between the lugs without care where exactly it was on the lugs (besides direction which is obviously important). Now reading the manual, I'm seeing a note about specifically where the diode should be:
"Coil Part Numbers ending with a "T" signifies the Diode is on the top of the lug (on the coil-winding side); Coil Part Numbers ending with a "B" signifies the Diode is on the bottom of the lugs."
I figured a lug is a lug. Would misplacing the diode on the lugs prevent the flipper from working? I'm just trying to be really cautious right now because I've hit a wall at this point.
