I'm trying to help a friend out with his satin doll pinball machine from Williams.
I have "cleaned" the stepper unit itself but it still will not go from ball 1 to 2 , 3 etc.
I have adjusted the "springs" to no avail.
It seems it's not getting a long enough pulse to step up completely every time.
I'll check out the coil and coil sleeve and they look fine along with the coil stop.
I'm just wondering if the item that pulses it if there's something going on with that.
Any help would be appreciated thanks.

Thanks for the reply!!
The stepper unit will now step through correctly but I'm having a very odd issue that I don't understand.
If I press for a two-player game it never plays one.
For instance if I push for a two-player game player one will play ball one and then player one will play another ball one then Ball 2 and ball two etc.
I don't know how for the machine to get the player two.

Yes, when the start button is pushed the 2 nd time is does unlatch the relay.

When I have the playfield lifted, second player score sometimes work,... as hard as that sounds.
Is there anything underneath the play field that could be adjusted?

Will do, thanks.

Thanks for all of your help pinballdaveh!
Machine the issues have been solved.
Now the only thing left is what pulses the 1000 point chime. It scores the points but no chime.
