The root cause was the problem I am going to describe in detail, the timer stepped to the 8th step and shut the control motors off before the register cycle had completed. The result was that control unit switch 16A stayed closed keeping constant current on both the Sequence and Winner Unit reset coils, followed by FIRE.
"Hey Jeff, this can't happen!" "The timer resets every time I press
the "R" Button, right?" Yes, it does. Now let me explain what causes
this "impossible" situation.

"OK, so what's the big deal, SW 14B is open during the payout cycle, right?" Wrong! It is open during ONLY PART of the payout cycle. SW 14B CLOSES each time the Replay Cams passes from position 12 through index to position 1.
To solve this problem, move the leads off SW 1A and put an additional switch on the stack on the outside of the Search Disc. This stack contains switches that prevent the R Button and the Magic Screen Buttons from activating during a register cycle. This simple modification will prevent you from having a fire similar to the one I am fixing for Doc Morrow.
I initially thought you could simply move the wires off SW 14B but if you do that it is possible for the game to miss the count pulse needed to advance the timer for 5th ball detection so that won't work. SW 1A always works because it isn't activated until after the 5th ball has been shot.
Note: using this method the motors will shut down very quickly after the 5th ball is shot - which is ok. If you want the original 1-2 minute delay, wire the extra switch in the search wiper stack in series with switch 1A
