Hello. Trying to figure out the name of the solenoid coils on my Williams Flash pinball machine that are not working. The coils are not firing to reset my drop targets and the ball return coil is not firing. I think that's the name of the coil that shoots the ball back in the position to be fired again. I'm trying to find the proper coil name and the corresponding transistors but my manual doesn't mention any solenoids called drop target solenoids. If anyone would know the proper names for these that would be most appreciated.

Well I removed the driver board and found 4 TIP120 transistors either cracked or with chunks blown out of them. These are solenoids 1 2 3 4. 1 is a Ball release, 2 Bank reset (Top), 3 Bank reset (Bottom), 4 Bank Reset. Not sure if the transistors are just old and died or if there is an underlying issue that is making them fry. They're so cheap I guess I'll replace them first and see what happens.
