Hey fellas, I've been referring to this forum a bunch over the years , but finally needed to create an account for some help,, so this is my first post. I'm working on a friend's 06 Arctic Cat 700efi that has no spark whatsoever and am kinda at a loss. To begin with, he had tried to fix it himself so he had replaced alot already...I know, I know lol. This is what has been done; New plug twice, new coil twice with new one ohming out great, new stator, new rectifier, and new starter solenoid.
. The biggest frustration is that I've got no codes. ECU shows that I'm in neutral and my brake safety switch works. I also show 12.5v at the tilt sensor pin on ecu which I assume is correct and then if u flip, then u lose voltage. Am I right, or no? Only other things I can think to do is replace Crank position sensor, get a peak voltage meter and read my peak voltages, or replace ecm which obviously is last resort.

I also verified the pulse coil. Thank you in advance

 

May try looking at the wiring harness stator to voltage regulator
