Quoted from edward472:The 2 fuses on the left of the second picture are the same fuse. The schematic is just showing 2 wires come off that 1 fuse. 1 wire goes to the tilt relay and the other goes to the coin unit.
Two different fuses for two different circuits. One for backbox lights and one for playfield lights.
To my eye, those wire colors in your photo indicate these are (top to bottom) backbox lamps, playfield lamps, coils, main/line. This matches my WMS EM games.
If you can't ID the wire colors in your game (vs. color codes on schematic at lines on both sides of fuses), you could remove one fuse at a time and see what doesn't work. Although when you remove the coil fuse you will have to manually press the lock relay in briefly in order to see any of the playfield or backbox lighting, as the lighting circuits are normally enabled by this relay coil.
