Hi guy's, I'm an aircraft maintenance engineer for Air Canada Jazz and have been there for 14yrs, last 5 as crew chief. Have been in the industry since 1997. Probably can't offer any services to anyone unless you own a multi million dollar jet but I'm pretty good at fixing almost anything. Lol...
Ok the 7 volts is gone from the switches, only 1.5 but I think that is the strobing from the mpu. Don't know how I stopped it but there must be something in a harness, I will further take apart and inspect. However the weird switch issue is still there. Luch when you get home try on your...
Or do you mean the giant black box that the wall plug goes into. If that's what you mean this game doesn't have one. It's the only game I have that doesn't have it.
Since the metal on the switch is physically touching the return line on the matrix if I touch the ball to it and then the side rail ( ie ground) would this not pull the line low and register as a closure on the entire return line? Does anyone have an early ss Bally game they could try the same...
Your right we have ruled out the roms. There's got to be a short on the playfield. With just power hooked up to the playfield from the transformer every metal switch is reading 7-8 volts a/c. Even when I pull fuses there is a small amount of a/c present. With all the strobe lines removed and...
That's basically every switch. Lol. I might start removing switches one by one till I find it. What's also strange is that it is showing switch closures that are not even switches in this game. I am determined to find this if I have to take the game apart piece by piece just to say I fixed it. Lol
Troubleshooting done so far. Disconnected cpu connector j4 (switch matrix plug) and checked all pins to ground and also checked the pins on the board ( found no continuity to ground). I have disconnected ( de pinned) every strobe and return line one at a time and checked in switch test with a...
