Game plugged in and switched on, fuses good, but nothing lights at all.
No lights and no power after storage: dirty hold relay
Cause: On Gottlieb (and many Bally and Williams games) power leaving the transformer passes through the contacts of a hold relay in the bottom cabinet. If its one or two switches are dirty, nothing downstream gets power.
Checks
- Check the fuses first.
- Find the hold relay: it is energized the whole time the game is on, so it is usually the most heat-darkened relay on the bottom board.
- With power on, push the relay in by hand and watch for the lights coming on.
Fix
- Clean and gap the hold relay contacts.
Unplug the game first: the power cord, fuse block and transformer primary carry 115 V line voltage.
