Looks like the schematics don't show the diode placement for every coil, but instead give a diagram that should cover most of the coils' wiring. You should have the power wire on the lug with the *banded* side of the diode. That goes for all the playfield coils on that game, as far as i can see (though the flippers are wired a bit differently).

Might as well go over the rest of the coils and confirm proper diode/wiring orientation, as it will damage the driver transistor(s) on the driver board and possibly more if wired incorrectly.
