One is to help keep the points from burning, but really the far more important job is that the coil and cap form a ringing circuit. WITHOUT A CONDENSER, most cars will not run. The spark will be extremely weak

I know it won't make a difference with the cap on or off, but it's obviously easier to see with the cap off. One set of points sparks/arcs quite a bit, but the car seems to be running alright. I always assumed the condensor was there to help keep the points from arcing much.
