As they were rather worn, I recently replaced the lower sling-shots on my Cue Ball Wizard. During reinstallation, I accidentally wired the right coil backward and immediately noticed that it was not working. A quick check revealed an short across the diode and a blown fuse. After fixing/replacing everything, I now have a coil that is stuck in the on (outkicked) position as soon as the game starts. I'm guessing I need to replace the associated FET but, frankly, I'm not sure since I'm not an electronics guy. Any help on a path forward would be greatly appreciated. Thanks!

Thanks for the quick response, that gave me the confidence to pull the board and replace the FETs. I already had some on hand since I was going to replace the missing knocker FET. I replaced both more easily than I imagined and now everything works. I noticed that the one I replaced showed a short across the pins so I guess I can just troubleshoot FETs by checking resistance between pins next time? Thanks again!
