Re: No Spark
No the ICU takes power from the battery same as rest of the electrics. It is orange/white (not sure about this, maybe it's orange/red). Anyway one wire appears at all 3 coils. This is the hot one that supplies power, with ignition on etc. it should have +12V at both coils and the ICU.
The black/white is earth same as round rest of the bike.
That bit coming up from the generator is the pulse coil. green and white wires or something like, that is signal generator which tells the ICU when to fire the sparks.
