1960s and 1970s Williams electromechanicals sometimes will go to game over
rather than blow a fuse. The most common short to cause this is a bad coil
or relay that when activated, immediately ends the game. If this coil or
relay happens to be activated as part of the start up sequence the game will
never leave game over mode! It is possible that the short is not a bad coil
or relay, but a couple of shorted wires. Check the relays in the bottom of
the cabinet that no screws or washers have fallen into the switches. Also
check that the solder terminals of the relay switches are not touching. It
is also possible for the wires on the back of the scoring reels to short
causing this problem.
