I am currently trying to resolve a WOZ ECLE problem and could use the assistance of the great Techs here on Pinside:
Problem: As soon as I turn the machine on, the upkicker to the castle playfield and ball lock bar solenoids fire continuously (munckinland playfiled)
What I have done:
1) Checked the switch matrix, shows both optos as expected for the solenoids to fire.
2) I have confirmed that the Optos, Cables and Opto boards good on both components
I figured the issue would have been somewhere along the opto chain but that is clearly not the case.
What else should I be checking?
