Ok....I have finally been able to revisit this. I've gotten to the point where I have totally removed the playfield and the associated Jones plugs connectors from the mix. I've gotten to the point where manually tripping the game over and reset relays allow me to start a game "blind" (meaning I can now go manually activate the 10s, 100s, 1000s, 10000s relays).when I manually activate these relays I get chimes....and on 10s, 1000s and 10000s I get the reels to turn each time. When I hit the 100s....I get chimes but no reel movement. When I purposely set all player one reels to anything other than zero and manually activate the no 1 score reset relay all reels begin to reset and eventually get to zeros.
By this logic....in my head...I'm thinking issue with the 100s reel since it does not move when I manually activate the 100s relay.
Is my logic sound? If so...I assume I should check all switches on the 100s reel as well as the coil?
