Having weird issues - As I was looking under the playfield on my EBD -LE, I noticed that the 2 yellow wires going to the center Thumper Bumper were loose. I resoldered them (3 times so far) and now I am having weird issues such as the 2x, 3x. and 4x drop targets will not score when dropped, the thumper bumper will fire on it's own causing the 4x light to light up, the left flippers sometimes get stuck.

I tried to resolder these connections again and when I went into test mode, switch 03 (4x target) light up as bad. I resoldered again (3rd time) and now the 03 no longer lights up during test but still have issues.

Does any of this make sense - I am thinking there is something in common with these wires but an not able to determine what it is.

Any help is appreciated - this machine is driving me crazy!
