uh oh, there isn't one. all there is is the box before the coil, ign module? that plugs into the coil, but it might be supposed to be attached to the coil? and it might be the power transistor if it plugs into the coil. the wiring looks ok but i could be wrong. the coil high side has 10.8 volts and drops to 8.7 low is .07 and gains to .13 and that is coming out of that box (ign module?, power transistor?) if these numbers are right then i think the coil is shot, also if that box is the transistor it is not grounded out right now, should it be? any clue? none here
