Good afternoon. Working on my WMS Space Mission. Restored it mechanically once when I procured this machine from a sand pile in Myrtle Beach South Carolina several years ago. Every switch, every step unit, checked and repaired all the lose wires. Been a solid restoration and it has stood the test of time.
Regrettably it's been moved three times since due to upgrading homes we lived in. Running into one roadblock that I have not been able to locate in the forum.
My Ball Release is firing. Just not enough to umphf to get the ball into to the shooter lane. I have worked through the schematic. Cleaned the 3A & 4A switches, also cleaned the pulse score motor reels. Then decided that I've gone that far decided to clean all the score motor contacts. Also cleaned the relative Outhole and Ball Index relays and went to the score motor and checked the score stepper unit as well as the player control unit. Tested the A22-550 Ball Release coil with the Ohm meter against the other with the credit unit in the back box. They Ohm out the same value.
At a bit of a loss and think that I went down the right road. Looking for any suggestions on this matter. Much appreciated!
