Yeah, the wiring diagram seems off. My bike doesn't have a tachometer - only a mechanical speedometer and indicator lamps in the dash. I mistakenly followed the blue/wt wire back to the relay starter - need to double check that and find where my coil voltage originates.
Edit -- the "k" from the chart blended with the ohm symbol, missed that. I'll run the test again in the next couple days and post findings.
