Quoted from dsquared_314:Where do I look on schematic?
The 00-90 Unit relay (FS) coil doesn't reset. You can see that on the schematic at 7E, only the M and N relays activate it.
The Advance Unit relay (KS) coil should reset at the beginning of every ball. You can see that on the schematic at 19E it resets through a switch on the Add Player Unit relay (P)
