Twilight Zone
Bally, 1993Hooked up 2 mods that draw power. First few plays are fine. Then clock broken error started popping up. Now whole game just shuts down and resets after a few plays. I'm a newbie to pins so no idea why this ts happening. Game is in the garage. Could it be the cold? Help.
Sounds like your 5v is on the way out. Start here, and follow the guide exactly:

Besides the above guide for the resets, did your mods blow the 12V fuse (F116)? Is your clock motor running when you boot up the game?
Clock runs and sometimes doesn't stop. Fuses still ok. Should I pull the mods before they fry my boards?
Reseat J101, J102, J114 on the driver board and J210 on the MPU first and look for any burnt pins on these connectors.
