indasevens,

You should have a 3-pin CDI just like mine. Hearing it whine is a good first step, but the instructions HarryD has shown are the basic ignition checks you will have to make. In particular:

2) Verify that the CDI is producing power to make a spark. You can do this with a "telegraph" test. Take the high tension lead off of the center of the distributor and put a spark plug on it. Ground the threaded part. With your plug attached to the center lead, open the distributor, remove the rotor, place your key in the run position, and manually open and close the points. Each time you cycle, you should see a spark from the plug. If you do not, you may have a bad CDI.

This is an excellent test of the CDI, and combined with the other instructions, should lead you to a working ignition system.

Best of Luck.
