Switch issue with No Fear

I have posted this in the pinball help group on Facebook but would like to see if i can get any additional help here.

During single ball play I noticed that a 2nd ball was getting kicked into play. Went into switch test and found the following:

left return and left sling both register when either switch is closed.

same for spinner and right outlane.

same for subway and “unused”.

So I’m guessing when you hit the spinner in gameplay the right outlane was also registering making the game think the ball drained and thereby kicking another game into play mistakenly.

Is this a diode gone bad? Any help would be greatly appreciated! Thanks, Mike

I think you are right about the diode. Which one uhhhh…
