WD-40 Posted July 26, 2020 Share Posted July 26, 2020 You need to check the AC voltage coming from the stator. Unplug the stator connector and start the bike. Set your multimeter to AC voltage and measure the voltage across all the combinations of the three pins on the connector. Measure the voltage at idle and 5000 RPM. All the combinations should show roughly the same voltage. It'll should be roughly 20V at idle and 60V at 5000RPM. Quote Link to comment Share on other sites More sharing options...
