I got a Six Million Dollar Man pinball machine that has a jumper wire on test point 1 and test point 3 on the solonoid driver board and everything seems to be working correctly except for @ 3 bulbs under the playfield that will not light up. If I remove the jumper from the driver board, none of my solonoids will work. Is there a way to remove this jumper and repair what is needed? With that jumper where it is, what is it bypassing?
