Gottlieb reset bank solenoid and S start relay run on 120 V
On many Gottlieb EMs the big reset bank solenoid and the S (start) relay are powered from 120 V, not the 25 V used by most of the game. Treat their wiring and contacts as line voltage.
120 V on the reset bank solenoid and start relay: switch off before touching them.
