Really helpful Chris! Appreciate the tip 👍🏼

I have a few banks of lights on my 1990 Bally Dr. DUDE pinball machine. I think the transitor for that bank of lights is blown. I got a multimeter and followed your video. The problem is I don't know how to replace the transitor or where to get a new one. Do you have a video on how to replace a transitor? Thank you for any tips!

Great tip thank you!

Do you do this if it's still installed and powered up ? I'm trying to fix my 91 Terminator 2 and it's driving me nuts 😅

You have to remove at least the solenoid drive connectors from the lower edge of the power driver board. And yes. Conduct the test with power off.

​@ChrisHiblerPinball thank you so much ! It helped me figure out what it wasn't lol . Traced it to a bad power wire . BUT! Now my ball lock switches which there are 2 and the lane change roll overs so 5 total switches aren't responsive!!? If you can help please do I'm at my wits end and my pocket book is as well 😅 I really want , no need this pin up and running. It keeps me up at night . Thank you

@ hard to say without more info. I’d encourage you to ask the question on PinSide.com

I have faulty Q95 which doesn’t show up using this test, but Q91 tests faulty but works ok. Any ideas. 15.45. 28.2.23. Thanks, Cliff.
