Hi, I have an 81 Suzuki GS 650 that I had running until I reassembled it. I lost spark out of the left side coil. The right side was only on 1 inside cylinder but both are firing now. The left side + has 12v on the orange wire into the coil & feeds to the - 12v but when I put on the white wire it goes to ground. I have traced it to the igniter module harness to the module. Is it typical to have a module go out like this leaving 1 coil to fire only?
