I am stuck on the start up sequence, and need a sanity check. I think the issue is the AX relay, but...
When starting the machine, the Lightbox sequence will go to "zero", the drop targets reset, and the score reels all return to zero. The balls to play unit indexes up to light up 5 to play, but continually hammers as if to go to 6, 7, or higher to play. Also, the R relay does not energize, thus the TILT light is always on.

So my questions are: When is the AX Relay Reset supposed to energize? When does the Hold Relay energize to turn off the TILT light? Am I correct in thinking the issue is with the AX (Reset Completed Relay)relay?

I can't find a start up sequence for this machine, and the generic notes I can find are not helping me. Thanks in advance.

Update - narrowed down problem to AX Reset Relay not pulling in - I'll keep working at the cause. If I manually trip the reset relay, then nothing was happening. I traced that down to the machine not sensing a ball in the ball kickout hole. I think I am missing something, because there is nothing that activates the the switch. See the pics. The Hole Switch Arm (C-15708) looks good and appears to match the parts manual.

I can't find what I am missing, so if anyone has a picture and a part number of what I am missing, I would appreciate it. Thanks

Dirtflipper - Thanks - I thought there might have been a wire form that was missing. I was able to move the switch stack over the plastic lever and that part now works. I didn't think there was that much play in it, but there was.

Finally figured out why the ball count unit kept hammering - the problem was physical. The switch backup plate (?) was bent, which did not allow the contacts on the stepper unit to make, which in turns activates the AX relay. When I straightened out that thick metal piece, that allowed the stepper unit to advance past 5 balls to play just enough to where the contacts at the bottom of the moving contacts on the outside of the stepper made it to the rivets.

My words are probably bad, but I am attaching a picture that will hopefully make it clearer.

I don't know how the back up plate got bent, but who knows. I did get three games in before she started to act up, so back to the drawing board.
