Very good dissertation on relay coil snubbing by Dan Schaefer. So here's my 2c...
 
A year or two ago when my spam can came back from its annual, a neat little diode was mounted across the starter relay coil. The mounting was carried out by crimping two terminals onto the diodes wire leads. So, as expected the diode had vibrated one end loose after about 20 hours. I pondered the problem and came up with the idea of mounting an ignition capacitor across the relay. It's cheap, has great mounting lugs and terminals and does an adequate job of snubbing the back EMF from the coil.
 
As I said, it's only 2c worth.
 
Right Rudder!
