Service log
Everything you record stays on this device.
Service notes: Magnet coil: 4.3–4.6 Ω (vendor) across the coil, game off. A magnet that never pulls is the driver transistor Q34 and fuse 5A S.B. (under the playfield) first, then the coil; one that stays on is the transistor. The three Power magnets and the upper flippers get their 50 V from the Extra Flipper Supply board A-15416 in the backbox, still to be measured; Operations Manual p. 3-9 shows the wrong connector for the magnet transistors.
