I just checked the primary coil resistance on my bike, and it's 1 Ohm. Wonder if this makes a difference compared to the 0.7 above... :think: (I'm not too familiar with the ignition system's details).
I also measured the secondary coil resistance but I got no reading on the multimeter. Connecting the multimeter to any of the coil's outputs and again any of the primary coil's terminals, made no difference. There was no Ohm reading on the multimeter (yes, I did use the right scale

).
Last bit of information: the coils are made by Champion.
