The score motor doesn't stop spinning until the reset, (or reset completed), relay is energized. 1 of the 3 switches on each score reel in the head makes at "0" and when all 3 are making, completes the circuit to the reset relay. Once this relay energizes, the score motor stops spinning and play may begin.

The ball release coil is supposed to remain energized at the end of the reset, and doesn't turn off until 1 or 10 points are scored during play. There is a normally closed switch on both 1 and 10-point relays, (not score reels), and once either are energized, will open and turn off the release coil.

On the credit unit, since you said the peg contacts the switches at 6-7 on the free play window, simply remove this peg, it is threaded on. In private play it is no longer needed. You should now be able to manually step down the replay unit to "0." Simply close all 3 switches permanently for free play. No further work should be needed on this unit, (unless it is not stepping freely in both directions).

Best to get the score reel coils, install, and see how things go then. Thus far, they are the only parts you need. John's Jukes in Vancouver should have the coils, (thinking this will help with the shipping).

Since your match light works at the end of the game, the game over light bulb in the head must be burned out.
