Dan Schaefer. So here's my 2c...</FONT></DIV>

<DIV><FONT color=#000000 size=2>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.</FONT></DIV>
