Default 1994 580 EXT EFI (no spark)

Please help. I have a 580 EXT EFI with a no spark problem. Ive looked at everey wire even took off the seat. Ive ohmed out coil,stator,both trigger coils. replaced timming trigger coil. still no spark. tried new cdi still no spark.. I read a lot from Blaine but what my sled has is only one brown wire comming out of motor in the four prong connection not 2 browns ..I grounded the brown to isolate wire harness. also bypassed TSS. STILL NO SPARK. Batt is at 12.05 volts.NO codes on ECU.
