how do you test a cdi and coil?

I have a 1995 Polaris 425 4x4 Magnum no spark. New stator ohms are correct on stator. Need some help on testing the coil and cdi. Can anyone help me?
Thanks

You cannot test the CDI. You can check the coil though. Use an ohmmeter to check continuity between the coil ground as well as the ignition wire. Resistance should be around 3 Ohms. You know if the CDI is bad by process of elimination.
