Got a top card I am trying to bring to life. Got schematic too. Problem is bill return coil is staying energized. I have checked return switch, O relay, motor switches. What else is there. Also the target switches are not scoring or chiming but the relay bank switches drop like they are suppose to. Cant find on schematic which contact conteols the target scoring. All scoring relays work fine. Any help would be great. Thanks

I should have clarified its the ball return coil. Seems fo stay energized. I tested switch an it works fine game goes to game over on last ball. Checked motor switches all looked good. There is a 5A switch I am guessing is on the A relay. They also look fine. Stumped

Which section do you need to see on schematic. I can post part of it or PM. I have traced everything to the ball return. Somehow its getting constant power and O relay isnt energized.

Well went over the schematics again checked everything associated with ball return coil. Still stays energized. Also target switches are not scoring or chiming still. I did notice that rollovers score but are scoring wrongfor 5 balls rollovers should score 1000 for 3 ball play and 500 for five ball play. Instead they are scoring 10 points for 5 ball play and 100 for 3 ball play.

Tested ball return coil came out with 3.3 ohms. Suppose to be 2.5 is that ok ?
Do you think on the ball return coil it could be shorted. It is not burnt and it being shorted would it stay energized. Thanks

Still no luck. Gonna swap coils.

Nope not the coil. All switches look fine. Disconnected motor and relay switches one at a time then put them back. No change. Ball return stays energized and and targets dont score. Grrr

Turned out to be a jones plug on motor board misaligned. Jim on RGP pointed me in the right direction. Now I have to figure out why targets arent scoring.

All targets and 2 rollovers. Turned out to be contact 1a misadjusted.
