Instead of being smart and practicing a little on an old circuit board, I jumped right into soldering the wires to my G27's shifter board. I tested it on my pc and in the logitech profiler the O button (same place as playstation controller, the right black button) was being pressed rapidly and the force feedback was going haywire. The O button still worked and would make the button say on, as did touching the two wires I soldered. I knew something was wrong so I took the board back out and when I removed the wire from the ground (opposite side of the board says J12) the blob of solder came out with it. I replaced the blob and tested it and everything worked fine. When I was putting the board back in the blob fell off. I fixed it again, but this time when I tested it there is a big problem. The black buttons work fine (other than making the force feed back turn on and off and makes the wheel spin around like crazy), but the d-pad and the red buttons are registering as 2nd gear. On the shifter all the top gears (1st, 3rd, 5th) do nothing and all the bottom gears (2nd, 4th, 6th, reverse) register as 2nd. Hopefully someone out there can tell me what is going on and knows how to fix it. My guess is that on the ground points there is something underneath those little blobs of solder and when it broke off the 2nd time it broke that off as well. If all else fails I may try to put it back together and send it off to Logitech and hope they think it was an error during manufacturing, find a used shifter somewhere else, or *gulp* spend another $300 on a new wheel.
