My Williams IJ is intermently losing power suddenly when the ball goes into the center trough and is loaded up into the idol. When the idol starts to turn with the new ball just lifted the power goes out before the turn to the next opening is complete. The power comes back on and the idol turns and spits the balls out and the game is gone. I have a video which I will try to upload if the site will accept it. There is only one message when test is run and it is for right ramp
made switch which is odd cause that switch is working fine. I’m not a highly skilled pinhead so I am limited in what I can track down on my own. Any help is appreciated!

I wonder what your 5 volts is at the cpu when this happens. Does IJ reset with both flippers hit at the same time? Does game play without resets with idol disabled?

Maybe 12v opto circuit is going crazy with idol moving. Does it do this in idol test in menu?

You could try this link: not sure how much you know.

Also, idol looks painted. Someone took it out? Maybe pinched harness or damaged opto wiring?
