Put the multimeter on continuity or short test whichever you want to call it. The one that makes sound when you touch the two leads together. Take one lead and put it on the sbce on the clip. Hold the clip where the part that clips to the flasher motherboard is facing you and at the top. The words e3 flasher wrote on the ribbon should be visible and on the left hand side. Take the other lead and the 3rd pin from the top on the right side of the clip that clips to the e3 flasher is the sbce. You should get a short. Now take the other lead and go to the end of the wire where it connects to A and you should still get a short if it is going all the way through. The same for your sbe point. Start at the clip itself. Should have a short between the 4 pin on the right hand side of the clip that clips to the e3 flasher board and the sbe. If so then try between the nor tristate and the 4th pin from the top on the e3 flashers clip. Should have a short if it is good all the way from the flashers clip to the ps3 motherboard.
