I'm assuming driver board issue but looking for second opinion on what to look at. After my Baywatch has been on for 30-45 minutes the plunger coil starts to fire. This happens even if the game is not being played. Thoughts?

When I play the game it works correctly. Honestly, since the coil fires even when the pin is not being used I figured it had to be something else. I'll take a closed look at it.

After more review the Vertical Up Kicker fires twice followed by the ball shooter once.. Always in a series of three coil fires. Any thoughts?

Found that when I touch the trough opto board it causes the the coils to fire. I need to place an order for PL tomorrow for a different reason. The board is $7, not even going to mess with it for that money. I'll update once it comes in.
