Hey fellow Pinsiders,this is my first post. I am a union pipefitter/plumber by trade so my knowledge of electrical is very limited.I do know what a circuit is and I know how to use a multimeter and I can solder wires ok but beyond that I am somewhat challenged. I recently purchased a 1979 Bally Silverball Mania that was not working. The MPU had lots of corrosion on it so I took a chance and replaced it with an Alltek which brought it back to life. I did change all the bulbs to single SMD leds and replaced all the rubber bands.The pin plays and looks great except that there is one bulb that does not light. It is the "N" in Mania which is lit by hitting the "N" target. I did clean the contacts on the target but that did not help. No voltage at any time is getting to the bulb socket even when in the test sequence. I did notice that similar targets have a small disk capacitor (0.33uF 12V Y5F). This capacitor seems to be missing on the N target, in fact you can see where the it would have been soldered to the terminals on the switch. Would the absence of this little cap cause the issue? The pin came with all the original schematics but they are absolutely confusing to me. I am out of my element on this, could someone with more experience than me point me in the right direction. Thanks for any advice.
