Junk Yard - Fridge solenoid keeps firing

[Neoretro]

Hi All,

Finally got my crappy colour DMD changed for a big screen Stumblor DMD on Junk Yard.

Went to play a game and the fridge randomly fires its solenoid, sometimes firing a ball. Occasionally the shooter lane will auto fire one too but not sure if that’s related to the same issue.

I’ve gone into switch test and the Lock Up 2 intermittently fires. I assume this is what’s causing the issue.

Does anyone know whether this is a switch or an opto?

The manual says it’s under the fridge but I don’t know what switch it is. Has anyone had this before?

Thanks

Dave

It's an opto, I can see to this tomorrow for you
