Looking at the game, I was guessing it has to be one of the two drop target reset coils - but per the Charlies' Angels manual - coil 6 is not used!! 7 & 8 are the reset coils.

Now - what's the chance you have the board accidentally set to another game, so it's looking to drive coil 6?

Exactly what i was thinking when after reading this thread, i checked the manual for Charlies Angels, and noticed coil #6 isnt used!
I thought of this yesterday but neglected to post a reply
