the coils controlling the coin rejection are called "coin lockout magnet #1-#3" on the schematic int he "replay subtract .." section (middle area).
manually pushing the coin switch down and releasing will narrow the problem down.
if you have a voltmeter and stick on probe on the orange wire on a coin switch and poke the brown/white wire on any of the coin lockout magnet coils and don't see 50VAC, it's probably either the front door connector plug pin BH or reel mech switch #6.
if the coin/credit relays are all unpowered, the only other thing it could be is a reset control relay (that relay should be unpowered), reel mech switch #7 (also unpowered).
if the anti-cheat relay is unpowered, push the armature plate down onto the coil top. If it doesn't stay there, the 50V fuse is broken or the fuse clip is weak/cracked/broken. The fuse holders on bally games eventually fatigue and don't hold the fuse snugly. If you remove the fuse and bend in the clips and they move easily or fall off, you needed to replace the fuse holder anyway.
