Hi,When cranking the coil power wire should have over a hundred volts.The black/orange to the black/white at the CDI shouldhave good battery voltage.Pickup coil blue to green and signal coil black to whiteshould have a small voltage pulse 2 volts for pickup and0.1 volts for the signal coil.Check the connectors and clean them.If these all check out then you might consider the CDI unit.Battery should be 12.4 volts DC or higher.WS
