I have a 2004 60 sdi that I have been dealing with a intermitten no spark and am looking for some insight. So far I have tested the kill switch, dess post, trigger, stator, coil, to find all in spec in a resistance test. Yesterday I thought I had found the issue I didnt have 12v feeding pin 2 on the coil I had found a dirty connection at the fuse block I had 12v now at the coil and checked now I had spark. So I reinstall the fuse block and put the pipe back in the sled go to try to fire it and nothing. So I am thinking it has to be a wire broken or breaking in the fuse block so I remove it and inspect the wires again and find nothing. So I recheck for 12v at the coil and I have 12v but no spark. So I then do the pin out testing for continuity between the coil connector and ecm and everything checks fine. I then remove the coil to retest the primary windings which check good again. So I am at a loss at this point and unfortunatey dont have another 600 sdi that I can swap parts off of.
