I got an ignition coil yesterday from a friend and I hooked it up to my
relay.  With a wire connected to the high voltage terminal I drew sparks
off of the the other terminals.  The sparks weren't very big though
(3-5mm).  I can control the speed of my relay now by putting a capacitor
across the relay terminals, but that just determines the speed of the
sparks.
I just don't get why the sparks are so small. If I just have the coil
and a power supply, everytime I brush the wire from one the coil's
terminals (not the high voltage one) with a wire from the power supply,
I get big bright sparks.

I built a pulse generator (circuit found at
http://www.geocities-dot-com/CapeCanaveral/Lab/5322/coildrv.htm)
but the results with it were non-existant.

What can I do?
