Pre-Fliptronics flipper coil wiring
On a non-Fliptronics flipper coil the blue/yellow (or gray/yellow) wire is the power side. The single center wire and the solid blue wire on the top lug go to the end-of-stroke switch and its 2.2 mfd 250 V spark capacitor, which are wired in parallel. The blue/violet wire continues to the cabinet flipper switch, the flipper relay on the driver board and then ground.
