I'm trying to set up a Grand Prix for 2 coins per play. I tried using the "two nickels per play" setting in the cabinet, but it doesn't seem to be working. Of course I'm not sure there is even a lead going to the coin door for nickels, and I see a dime and quarter relay in the back of the cab, but no nickel relay.
Was also wondering if there is a coin diverter that could be used with quarters for this machine and where I might find one?
