rattling dead klr. :-(

So I decided to look beyond the CDI at things that are connected to it and might affect it. I discovered that the resistance of the pickup coil is infinite (meaning that there might be a break in a wire or the thing is pooched). Does anyone know if it would be possible for a broken pickup coil to fry the CDI? It seems possible to me since the exciter coil provides energy to the cdi which waits for a signal from the pickup coil to release the energy to the spark plug. Could there be too much energy put into the cdi since it stops discharging or do the capacitors in the cdi have some sort of overload protection? Al

Sigh, bummer. I was hoping that there was clearance, but the noise he describes is starting to make sense. I'll have the bike here in the morning to begin the teardown. Sounds like I may as well plan on having an engine sitting on the bench for a bit. The AR15 will have to find a new hangout for a bit. Thanks for the quick response! E

I work with coils and electronics for my job (solenoid engineer). That doesn't make me an expert about CDI, but a break in the coil wire would cause a voltage spike at the break (if there was current flowing) not at the CDI. Curt Curt Van Weelden [Non-text portions of this message have been removed]
