*** See bottom of thread for latest issue. This first issue is now resolved. ***
The 1975 GTB Top Score restoration I've been working on since March (off and on) is almost done. I've done a full cabinet repaint, small playfield touchups, added all-new exterior cabinet hardware and legs, and have gone through all the mechanicals.
Last night, after putting the playfield back together, I fired it up for the first time since taking it apart a couple of months ago, and there are a few minor problems to sort out.
When I press the start button, the score motor starts and the Player One reels reset to zero. At that point -- according to the manual -- the player unit SHOULD step once and then the Player Two reels would reset. My player unit is not making that one step after the Player One reels reset.
If I manually step it once, then the Player Two reels reset and it starts a game correctly on Ball One. I can then play a game all the way through to Game Over correctly. So, I'm looking for some assistance in deciphering that part of the schematic that shows the Add Player Unit coil and why it's not taking that step after the Player One reels reset.
There are other more minor tweaks needed, but let's focus on this one first. I appreciate the wisdom and help as always!
