Sounds like your center electrode on the cap is shot. It should protrude about 1/8 inch or more (don't remember exactly). Mine went at about 500 miles as well. I believe it was because there was insufficient pressure on the center contact on the rotor. If there is a gap there, the arcing probably destroys the carbon very quickly.
