Capacitor Discharge (CD) Ignition?

I have a CDI box used for firing the electric turnout motors on the turnouts on my model railroad. 25V out to the turnout insures a loud and decisive "SNAP" and assures the turnout is thrown in the proper direction, all but eliminating derailments due to an improperly thrown turnout. Works very well, but it'll knock the **** outta you in the right circumstances.
