Since I bought my Whitewater a few months ago, the upper GI has never worked. I traced the wires back to each socket and the connectivity appears good. When I turn the game on the 5 amp fuse blows immediately. Something that was strange was that the J121 and the J120 plugs were reversed even though the game played normally. Nothing changed when I swapped them back.
When I bought the game, one of the GI sockets on the upper play field had been removed (had black like burning marks around where the socket had been), and the wire twisted together and wrapped with electrical tape. I have since added and soldered the socket back in. Any ideas where I should look next?
On the pictures, fuse 109 is missing. I pulled it for another test (and fail) of the F110 fuse.
