The Solar City I’m trying to fix is making it through step 8 of the Reset Cycle. The ball that is in the outhole kicks out, but the ball 1 light never turns on.

Initially I thought the issue was with the Q relay, but both the Game Over and the 1st Player Coin Lights work as expected. This should mean the M/B switch on Q is working correctly.

I think the player unit is in the wrong position after completing the Reset Cycle. The photo below is of the Player Unit after ball 1 gets kicked out onto the runway. If I actuate the Player Unit by hand, I can get it to a spot where Player 1 is active and the Ball 1 light is on. If I then play a ball and let it drain, the machine gets stuck in a score motor loop.

Thanks

Alberto

As the ball kicks over, it rolls over the Trough switch which should activate the Add Player Unit relay (P)

It looks like the part with the pins and springs is upside down. the arm with a single pin/spring should be on top and the arm with two pins/spings should be on the bottom.

ArgosySK, thanks! That was it! The Player Unit was backwards. Now onto the next issue, my Bonus Unit only counts to 9.

The Bonus Unit on this machine only makes it to 9, not 15. There is a physical stop under the gear that will not let the bonus unit count all the way to 15.

First photo is the starting position of the Bonus Unit. The second photo is as far as it gets before it hits the mechanical stop.

Can you talk a picture of the opposite side. (both positions as above)

The first photo is the final position when it hits that physical stop. The second photo is the initial position. The bonus unit is trying to finish counting to 15 and it can’t.

The bonus unit contact, that should close at initial position, looks like always closed and might need some adjustment. But first make sure the switch stack screws are tight.

Was the unit recently cleaned?

I am wondering if the spring is too tight.
Can you unwind in one turn? (You may have to move the switch stack out of the way)

Or there is is stop on the underside of the gear and the gear need to be re-positioned so the stop is on the other side.

you're missing the white tubular switch lifter on the switch blade and your ratchet is installed incorrectly.

the length of the switch lifter is critical for reliable operation ... too short and you won't be able to adjust the switches correctly (don't ask how I know that).

you should be able to hold in the reset coil plunger, spin the ratchet counter-clockwise and when you let go, it whizzes back to the stop bracket argosysk mentioned and stops. The pin on the ratchet only pushes the switch blades when the unit is stepped up to the top step (15 steps counter-clockwise).

below is blibb's pic from another solar city topic showing the ratchet in the unit reset position.

if ya get a chance, can you post a picture of the score motor? Either the timing diagram on the schematic for switch 4D is wrong or I have an odd score motor configuration on a solar city.

Stepper now works properly but the count is slow. Thanks for all the help with this. Plenty of posts here on the slow bonus sweep, lots to debug.

Congratulations Alberto! You're one step closer. The slow count is exactly the issue I was dealing with, so follow baldtwit 's advice for me, and you should end up with a machine gun stepper as well. The game is so much better with fast, accurate, scoring.

for slow bonus count:

1] the G relay needs to stay powered the entire time the bonus unit is stepping. If it is powering/unpowering, you'll miss pulses and the stepping will be irregular.

2] score motor 4D provides one pulse per score motor cycle (120 degrees). Score motor 4A provides 5 more during the cycle. If 4A not working, you get a regular but slow bonus step-up.

3] K relay switch with GR-YEL and BLK+RED wires needs to be closed unless you are scoring double bonus. K relay should only power when scoring double bonus.
