Hello,
This is my first post and first attempt at repairing a video game. I've enjoyed reading many posts here and am amazed at the knowledge of everyone.
I have a Baby Pac-Man that I am trying to repair. I have several issues with the game, such as the monitor is only displaying two colors, but that is for later as I may do a LCD swap. But for now, I am trying to get the Targets to pop back up and the ball eject solenoid doesn't work. I'm hoping to get some help/advice.
What I have done so far:
Targets solenoid:
Measured for voltage from ground to both terminals on the solenoid (NO-26-1900). I measured 47 VDC on one terminal and 0 VDC on the other. My understanding is that both terminals should have approximately the same voltage but only one does. Is this an indication that the solenoid is bad or possibly something in the circuit board? Is there a test I can do or should I just find a replacement?
Ball Eject:
The ball is supposed to eject when the right flipper is pressed. The flipper works properly but the ball eject solenoid doesn't activate. I found two possible issues; 1) there is no diode on the right flipper blades (I actually found it attached to the speaker magnet). I have purchased new diodes but not sure if this will fix the ball eject issue. 2) I found a wire hanging off the right flipper and not sure where it is supposed to go. It is white with green stripe. I appears to go to the ball eject solenoid but I'm not sure. I have looked at the wiring diagram but there's no color codes that I can see other than numbers. I assume the numbers correspond to a color but not sure.
I know that's a lot but I appreciate everyone's help and advice!
