I recently purchased 1978 Cherry Bell EM pinball machine. I was able to get it to play, but I'm dealing with three issues, wondering if anyone could provide some assistance. I do have the schematics. I downloaded online, bought a copy that's barely more legible than the online version, and also downloaded the better looking "Faces" schematics. I can also view a Williams schematic that's very similar to Sonic. I'm a novice at pinball repair, and struggle reading these schematics, but with a little help, I know I can get this game 100% I'm good with meter and solder iron
Problem 1: The bonus alley/chute to the right, with the ball kickout, only works when one of the two bonus lights light up (the bottom one). The playfield seems to work perfectly as long as that credit light stay lit. When that light is off, the ball hangs up in the kickout hole, the scoring continues to add until I hit reset, or manually trip the Aux Top Eject relay. Probably easy to figure out, but I've been beating myself over the circuit for so long, I've given up.
Problem 2: I've seen where this problem has occurred on other EM games, but can't remember where I saw the solution posted. When I insert one coin (or trip the coin switch once), with 5 ball setting selected, the first ball goes to player one, second to player two, Third to three, and the fourth and fifth ball to player foour, then game over.
Problem 3: If I ever press the red game credit button on the front, I see a spark on the first gear of the scoring motor, and the 15 amp fuse will usually blow. I took a volt meter to the credit button switch, and got 6v on one side, and 34 v on the other side. In the game's current setting, I do not need to press the button, so someone's going to say, just don't press the button! Yeah, but... I'd like to figure out what's going on here.
Thanks in advance to anyone who can help!
