I went back and checked and cleaned all the score reel switches and mechanisms. The switches are working properly when I manually advance the score reels. Score reels still reset except for 10,000s and 100,000s scores; and when starting a game the score motor in the cabinet and the two reset switches in the backbox constantly fire. If I manually set the 10,000s, and 100,000s scores to 0 game starts as it should.
EDIT to the post.
I am learning a lot along the way. There are three reset relays in the backbox. The third reset relay controls the 10,000 and 100,000. The first two reset relays continuously pulse at start if there are points on the 10,000 and/or 100,000 score reels. The third reset relay never pulses. The score motor first wheel controls the 1 and 2 reset relays and the third wheel activates the 3rd reset switch.
The switch on the first score motor wheel sparks blue when activated. The second score motor wheel switches appear to be adjusted properly.
