Make the GI come on at power-up by locking out the hold relay

Steps

• Bend every switch on the hold relay so it is closed all the time.
• Disconnect one of the wires to the hold relay coil, so the coil is never energized (no heat, no hum).
• Power on: the GI now lights at once.

Side effect: switching the game off mid-game no longer ends the game; it resumes where it was at the next power-on.

Unplug the game first: the power cord, fuse block and transformer primary carry 115 V line voltage.
