I have a coil for the drop target for the black door in the back left that keeps smoking up. The transistor on the main board was fried so we replaced it and no go.. So we put in a new board and it worked for about 10 games then smoked the same coil and transistor. Any ideas? Coil is smoked and transistor is also smoked again. Had a tech come over and do the work but I'm trying to figure it out myself until he can get back out. The coil is getting 76 volts after transistor is blown. Thanks for any info, this is my first pin.

Wow guys thanks alot. Let me check a few things here and I'll let you know.

So here's a pic of what's connected. The blue and brown is disconnected so I could still play the game. But if I understand this right one of the violet green wires should be on the other terminal with the blue and brown? It was getting to much power??!!??

Ok so I think this is right.. what do you think? Not soldered in just placed for pic. Thanks for all your help!!!

The black wire is not part of this system... It's in the background but looks like it is connected.. sorry bad pic. So all the violets together and the blue and brown on the other side by itself. If the blue and brown doesn't go there the coil wouldn't have anything on one of the lugs.

By the way I appreciate all the help with guys. This has been very overwhelming for me to try and figure out. So thank you for your time and input.

Awesome guys thanks!! Think it was burning up because that small violet green wire was not hooked up at all. So being connected to the diode on the board wasn't doing its job. In turn blowing up the transistor and giving it power all the time and burning up.. make sense? I'll get it hooked up soon when I get new coil and that board fixed. Thanks alot and I'll keep you posted!!!

Thanks dumb ass! Getting my feet wet fast! I'll keep you posted.

Update.. yep that was it! Everything is working properly. Thanks for all your help guys, I really appreciate it. Till next time lol.
