Wiring harness has been unwrapped and thoroughly checked from engine to fuse box. All wires rung out, everything tests fine. Flywheel was pulled, all ok. I have 4.5 peak volts from pulse coil at the igniter when engine is cranking. 12 volts to brown wire at igniter and good ground at igniter. 12 volts to coils but blue and white wire never go to ground (0 peak volts across coils). I have tried 2 igniters ( 1 new,1 used). Currently I'm looking for another mule in this area to test igniters. I'm open to any other ideas.
