Key On voltage measured at the coil connector, using the same Black/White hot wire as Positive
Yellow/Blue voltage is 12.5
Blue/Yellow voltage is 0 also probed wire at the ICM, it was the same.
When cranked, Y/B jumped to 16+
B/Y increased to 6
WHY?

Re: Low Voltage At One Coil
It's by design. The engineers knew the voltage would be low when the bike was being started, because a lot of power is going into cranking the engine, so they have the bike boost the coil voltage during the start cycle.
