Hey guys, does anyone know which transistor drives the beast layer pop bumper? The score switch works on it but the coil isn't firing. Thinking I might need to replace the transistor as I ran an alligator clip across all the Q transistors on the solenoid driver board and got all the upper pops to fire but not the beast lair. Wiring from PF to the back box seems fine and I have continuity on the coil and on J1 pin3 to the board, just couldn't locate the transistor on the schematics. Thanks

Thanks, I thought it was Q2 and it's dead to the alligator clip. Gonna order some TIP102 and replace it. I have TIP122 on hand but not sure if it's compatible. Thanks again.

When I try a jumper on the transistors Q2 does not fire the beast lair pop.

Yes sorry that is what I meant. I thought it might be a cracked solder joint but pretty sure I reheated J1 pin 3 when I checked the back of the board previously. I will check it again. But I have continuity on the pin in the connector and I have 43v at the coil so thought it I would look further back on the board. I tried an alligator clip from ground to the coil but it didn't fire, maybe it's something on the coil like a bad diode?

Ok yellow wire on the coil measures 43 volts, black-red wire measured only 3 volts. Upon inspection, the black red wire lug does indeed have a break in the coil winding on the diode side. Attaching a pic, hopefully you can see it. Interesting, first time I've encountered something like this. Can I solder the coil winding back together or will I need to get a new coil?

I went ahead and soldered it...success! Finally Paragon 100% working in all it's glory. I might still order a coil just to have on hand, not sure if that coil winding will take all the abuse from the pop bumper firing. Thank you kindly again for helping me.
