CBR929RR Ignition coils?
About a month ago I rode my 2001 929RR into my shed (because it's winter here in Australia). My CBR1100XX was a crash damaged bike which didn't come with the HISS key so I swapped ECUs around to test the 1100 but it wouldn't fire. I swapped the ECU back and now the 929 won't start. I did run the 929 low on fuel, but I've topped it up with fresh from a jerry can (I also race karts, so had plenty around).
In order to diagnose it, I've tested the injectors (they all fire) and the coils are getting correct signals from the ECU according to the oscilloscope I've got; it sits at 5v then drops to 0v to fire. I've pulled a coil and tested it for resistance for primary and secondary. I've done the same for the spark plug that came out as well. The spark plug was 4.9kOhm, which sounded about right. The resistances of the primary and secondary came out ok too from my research (can't remember what I measured, but one was low and one was really high - none were open circuit).
With the spark plug in the coil and the coil out of the block, I've run a jumper lead from the outside of the plug back to the -ve of the battery. When cranking I get no spark. I've tried earthing against the chassis and no spark.
I've tried heaps of different things, all with no spark.
Also in my shed is a CBR1100XX and a CBR900RR (which is in a lotus 7 replica), so I could try coils from them, or plugs from them, but they're not a coil on plug setup, so it would need a bit of dodgy test wiring.
The ECU is operating normally (the trip to the 1100 and back didn't hurt it), as proven by the signals that are going to the injectors and the coils. The fuel pump primes and the dash shows everything as normal.
Any suggestions? Do coils fail on these often?
