V=I x R....mr ohms law....check the resistance of the yellow pin from the connector back to the board! You already stated the connector is burnt! Most likely the wire has suffered heat damage as well. The harder the current has to work to get through the yellow wire and burnt pin/connection the low voltage on the end is the result. Check the resistance, then check the voltage on the input side of the connector...probably the voltage drop you are missing resides in corrupt yellow wire and connector....back up...follow the resistive path and ya gonna see exactly how or what is acting like a big resistor in the circuit. Just a few ohms makes a big difference...compare the resistive value to the other pins in the connector....really ya should have checked resistance first!

I think maybe someone misunderstood my intent. I offered the fix for free! I did not offer a board fix for free! However, I did offer to aid in that regard for a donation. Even that is left to the individual that phones. I do however post free air-time daily on several other sites! Considering what I do and the level, I really do not think a small donation is unheard of. Would ya rather donate 20 bucks and fix a 250 dollar board, or muck it up and have to buy one? Personally I would love to of had an opportunity like that in the day. I am not a young man....and have several health issues that require many doctors help. They essentially donate time for me and hundreds of others. I use the services weekly and I am quite glad to have that opportunity. But, each and every time I leave it is twenty bucks! And each and every person that goes pays it. I have thousands of schematics on files that I refer to. These were not free, some were acquired freely over the years but most came from Startek journals and pinball manuals I paid for. I presently own, and store hundreds of pins...likely to be donated one day to a museum....until that day comes this ole man continues to work in bad health to maintain an environment for them. Also...I think it would have been nice to post my message entirely instead of making it sound like I am raping folks. I've spent ten hours or more stepping folks through delicate repairs. I believe my message said...." I will help you fix the problem for Free, a donation is greatly appreciated!" I believe that is fair my friend! This very site appreciates donations, does it not? I also stated in that message my credentials. 45 years in the amusement industry, and, electrical engineer that you speak with. That is a very strong and dynamic duo coupled. The message I sent posted the fix and the methodology. Voltages were mentioned but nothing about Resistance!! Methinks resistance should have been measured before voltage but I did not see those from the posting. On a phone you can gauge an individuals ability to test and repair. In a forum it's very difficult. Presently I do mobile repairs in several states and rest assured my rates are half to two thirds less than my competitions. Peruse the pinball owners group and you will see that I offer a time slot for several hours every other day that is 100 percent free! I do this out of my personal love for pinball. I started playing at age five and at age 62 still play. I was repairing pins by age twelve, at least the e.m.'s. I am a dying breed in the Bingo world. If you own a bingo you know just how hard it is to find anybody...much less someone that is knowledge oriented with 45 years of experience. Feel free to phone anytime with an issue....my time is free....donations are greatly appreciated!!!

Also, I might reside in Va. but I was born and raised in North Carolina. It was the poorest state for a long, long, long time. Also...."donation" does not necessarily mean money! Many people give me old displays that I still have parts on hand to fix, or a backglass that half the paint has peeled off of and so much more. Presently it is my main source of income. Luckily what I have is paid for. Yesterday I fixed or about to fix a SB-100 sound board for a later model Stern. They are troublesome for even experienced electronic techs. It caused some heartburn for myself too, literally as I do have major Gerd issues. If you can find this board....that is ifffff, they run about 160-200 used. The fellow I am working with, and this has involved eight trips to his home, might end up with a fifty buck repair bill? I sure hope somebody uses my service....phone 434-333-1171....SB-100's are fresh on my mind!
