[QUOTE="user 89005, post: 1296660, member: 89005"] First day here in Southern Germany that brought out the fair weather riders, probably safer to be working on the bike! Yes, 12v at the primary coil side. No spark during the diagnostic function test. If I understand Donal's idea correctly, by pulling the ECU wire from the coil I should get a spark during the diagnostic function check. If I do get a spark then the ECU is bad, because the ECU is not isolating the ground and thus preventing the spark? Notes: I double checked that both wires from connector at the ECU to the coils have continuity. All switches, sensors and connectors are good in the ignition system. Issue is not a fast start nor are the cylinders flooded and I see no unrelated faults...except for the operator! [/QUOTE]
