Finally joined the Firepower club.

I've had this rag dog since about 2004. When I got it, it was sitting beside a garage in a barren back yard in South Dallas. I don't know if it ever was rained on or not, but by the mold growing on the inside of the insert, I'd guess at least once.

The glass and backglass were intact.

Of course, the mpu wouldn't boot and only "a few" of the solenoid drivers still worked.

The save solenoid didn't work.

The battery corrosion involved the entire lower right quadrant.

The plastics all ok, rubbers hanging out like a dogs tongue on a hot day.

Many hours of repair, both mpu board and driver board, rewarded me with a functional game that only occasionally reset or blew fuses.

Then I moved in 2005. Finally, last summer the game was brought inside the house, from storage in my shop.

The machine wouldn't leave audits.. Dead 5105. Now running again, no feature lamps.

Found bridge rectifier harness lugs falling off wires.. Now all is good, and restoration will begin soon.

I have enjoyed reading ya'lls posts in this thread.

Thanks.

Pawing through my Firepower parts I came across a baggie with four pop bumper caps.

Three of these, "normal", are as in the right side of the photo, the odd one is on the left.

Do any of you know the history on this all red, partly upside down, little freak of nature?

MDBradley, inspect playfield harness connectors 8P2-12/8J2-12 and 2J7-2/2P7-2 for un-cleanliness, like green corrosion on male pin female socket, or pin not pushed fully into socket, etc.

Your description is not a diode failure, nor a switch maladjust.. It is MOST likely a connection with excessive resistance..
