"Rodney, you didn't list the model (however the 150's are all similar at with regards to the ignition) and I am assuming that any kill switches you have are functioning and in the (on) position.

"You can check the stator with an ohm meter (multi-meter). The quick check is you simply look for continuity between the leads (which indicates the windings are intact).

I'm not at home right now, but will look up and post which leads you need to test since I assume you have a couple for ignition and a couple for the charging circuit.

Basically, you determine that the cdi is the problem by testing everything else as good - there is really no other way (at home) to test it..."
