I already checked everything, as in the manual. White and white-red 93 ohms, black-red and red 17 ohms, grounding to the ignition coil 0.2 ohms. I disconnected the black wire. Ignition coil wire and cap 11567 ohm. Yellow and yellow-red 20-23 ohmThat's 100 PEAK volts - it's just a pulse about a millisecond in duration of about 100v - 80 to 120v or more is acceptable.
The first thing to do when spark is lost is to unplug the black wire from the CDI unit - if that restores spark, the problem is connection related - if not, then it is ignition system component related.
cdi block is new, new voltage regulator, new stator, the only thing I haven't changed is the trigger coil
