I have a 1977 Williams Wild Card that did work fine. Then it just quit resetting correctly. If I push the replay button the score reels reset to 0 and everything else seems to reset correctly except the ball count unit. When the ball count unit is in game over mode it is in the position shown in the pics. Not sure that is where it is suppose to be in game over. When i start a game the ball count unit top coil in the pic just keeps firing and firing. That is trying to push the pin toward the switch. That cant be right can it? How is the ball count unit suppose to reset? Anyone maybe have a Wild Card they could take a video of the ball count unit resetting at the start of game? Maybe already have one. Do you see anything that looks wrong with the ball count unit? I have cleaned the ball unit as you can see in the pic. It does operate manually in both directions good. If you need anymore information please let me know. Thanks

Both of the pictures in my first post where taken with the unit in the same position. Here are a couple of pics out of the Wild Card manual of the ball count unit. When they say the picture is of the wipers in the reset position. Do they mean when the ball count unit is at 0 position or after the game has been reset ready to play. I will put 2 pics up of the wipers being in what the manual shows as the reset position. They where both also taken with the unit being in the same position. So could the wipers be 180 degrees off? If so I have no idea how unless the wiper nut is that loss and let it pull out and spin around. I don't think so but who knows. Maybe somebody messed with it without it being known. Thanks

Oh yeah. To get the ball lights to show up on the backglass the rod/pin sticking out of the gear side has to be over close to the lower coil the way it is now. See the red dot I put on pic. That just can't be right. I am thinking more and more it is off by 180 degrees. Very weird if it is. I am not where the machine is right now so I can't check it. I will dream about it probably. Thanks

I will put the white pin in the zero position. Then take the nut off of the wiper side and turn the wiper 180 degrees of coarse holding the gear side in. Any of them I have ever seen the wiper setup will only go on two ways. 180 degrees from each other. Unless this one is different for some reason. If I do that and it don't fix it I can just switch it back. I will take notes and make sharpie marks though just incase it is different. I have a feeling it will fix it. I was just very confused about it. Maybe that nut is really loose. I did not notice it messing with it though. Maybe the pinball ghost. I will report the results back when I get to it. Thanks

Ok I turned the wiper 180 degrees and that is what was wrong with it. But not all. Now when I start a game it all does start correctly except it does not start on ball 5 everytime like it should. It might start on ball 2 or 3 or 4 and sometimes 5. As you can see in my first post I have cleaned the unit good and put a light coat of super lube on it. The ball count unit moves flawlessly if I do it manually with the coils. So I am thinking maybe some kind of a pulse issue. Not getting enough power or something maybe. Anyone got any idea what could cause this. Thanks

I will check my schematic and check that out. I aimed to put this in my last post. I also realized today that every once in awhile after I got to the last ball and the game was over. when I press the start button to start a new game it would do nothing. I could then go under the playfield and move the score motor just a little and then pushing the button would start a game. It did this about 3 times. It is set to free play. Do you know what would cause this? Maybe the score motor stopping short or running over? Thanks
