I was installing pinnovators head phone jack on this machine. (which I don't think has anything to do with the problem.) put it together and now I don't have a single solenoid that works. I have 4.95 v at TP1 if that helps. When I run through the test mode no solenoid activates. Neither flipper will work as well. Still new at the electronics thing so be patient.

I've looked over all the connectors. No fuses visibly blown. What one connector would control all of the solenoids?

That was an awesome tip. I keep reading how you have to pull the fuses to test them but now with your post it was super easy to check them all. By using the meter, machine off, I found the culprit. I appreciate you taking the time to answer the post. Problem solved. Please resume to your game of pinball.
