Just got a Sorcerer from a friend in trade. It has an odd start-up issue.

When turned on, there is a set of numbers in display 1, and there is a "04" in the credit window. 00's in the ball in play window and nothing in all the others I believe. Previous owner showed me what to do. You hold in the advance button until you run the ball in play window up to 50 and the game reboots. It goes back to the way it was, and you run it up one more time. After this, the game boots the way it should and plays fine. I don't even know where to start with such an odd problem.

Anyone have a clue?
 
I think I just found my answer on RGP. Last owner said he put new batteries in. Odds are the holder is bad. It is in audit mode because the batteries are not being seen by the CPU.
 
It's more likely the blocking diode is open unless the battery holder is really crusty. Should be easy enough to figure out with a meter.

That's a pretty common thing with Williams games and batteries. It comes up on this forum from time to time as well. Once you've seen it once you will know every time when you try to boot a system 3-9 game with no batteries.

You can usually turn it off then back on quickly to get it to boot.

To say the batteries are not "seen" by the CPU is kind of misleading and not really true. The CPU has no real way to "see" the batteries. For some reason Williams programmed the games to boot like that when the RAM is blank (no battery power to keep it "on").

Williams pinball repair 101. If it looks like this you can be pretty sure the RAM is not getting battery power.
