All three stock flipper coils in WW are red (FL 11630).

The right flipper coils are linked together for 50V power - the upper right should have two BLU-YEL wires and the lower should have one BLU-YEL for the high voltage side. A problem there can mess up both flippers.

Your picture looks like the upper flipper. If the coil lugs are 1-2-3 (top to bottom), 1 is the two BLU-YEL; 2 is one of cap leads; 3 is the BLK-YEL and the other cap lead. The blue coil is also two steps higher power than the stock red.

Can we please see pics of the wiring connections on the lower flippers too, left and right? Maybe there's something going on there.
