Hello! First let me start by saying that I am extremely new to pinball repair. My wife purchased a fireball home edition for me for Christmas for about $400. Everything worked ok, it just needed some minor repair (new bulbs, flippers, rubber bands, etc.). I attempted to change out the right flipper coil as that flipper was a little weak as was the outhole kicker. This didn't seem to fix the flipper issue so I put the original coil back on. I read somewhere later that the end of stroke switch may need some adjusting so I did and the flipper works great! When I powered on the machine later, the outhole kicker energized but didn't release so I had to turn it off and disconnect the wires from the outhole coil. The game works perfect if this is not connected but as soon as I connect the wires to the outhole kicker coil, it will remain energized until I unplug it again. I don't know much about the schematics, was hoping someone would be able to point me in the right direction to get this back on track. Thanks in advance!

Hey. Thanks for the advice. I will definitely take a look at the wires. The first time that it froze on, I think I left it on too long until it fried the transistor. Since then the transistor has been replaced. I had read elsewhere that it could be a resistor somewhere, just not sure where to start. I have printed the schematics and plan on showing them to an electrical engineer at my work to see if he could point me somewhere. I'm grasping at this point!!

I will take a look. Thanks for the link!

Ok. At this point,I have checked everything that I know of to check. Would it be possible that of of the ic chips is bad and if so, how would I go about checking that?
