Just in case you don’t have the manual, here’s a pdf version of one. FWIW
This is the part on checking the CDI.
Here’s a variety of other info on my NX. If it helps any…

Again it failed to start first thing in morning, then it did start.
Finally it failed completely. Only then could I do the resistance tests outlined in the manual to be sure it was the CDI and not another electrical componet. ( Coils, wiring, etc.)
