Just when I thought all was fine with the "Add Bonus When Lit" lights. Previously I had a problem where the DX relay would not activate on ball 3 and turn on the the in-lane "Add Bonus When Lit" lights. (Posted as Top Score Dx Relay Question"
With the help of paulace and currieddog I tracked it down to a weak spring on the DX solenoid plate. Things worked as they should up to a point: At ball 3 the two DX in-lane lights come on. At ball 4 two EX lights come on. At ball 5 one FX light comes on. All good so far.
The new problem: On ball five, when non-score motor points are scored (10, 100) all five lights stay on. Still good. But any points involving the score motor turns off (resets) the DX and EX and four lights go out. Yesterday only the EX (ball 4) lights went out. This morning DX and EX lights go out.
The pathway to reset the DX and EX is on photo 3. The O relay switch, U relay, P5A, K make-break, Motor 1B. But also on this path is the FX which stays on. It doesn't add up. Unless the FX stays on since the player unit is on ball 5 and the snowshoes are touching the rivets that turn on FX. Just desperate speculation, not sure how that works. Very confusing.
I've looked during ball 5 when the score motor turns and the DX and EX definitely snap back to reset position. I don't see what would cause that.
One note: When I first got the machine, during start up the AX would stay on and the score motor would run endlessly. I followed the path from AX reset to the GR+RED "O" relay switch, cleaned and gapped it. Since then the AX shuts off and the game starts properly. I mention this since that's the same pathway to reset DX, EX, and FX.
Any help? I'm just going in circles thinking about it. Henry
