[AT] AT Digest, Vol 42, Issue 31

[Chris Britton]

No offense intended.. but I frankly don't care if he is the secretary 
general of the US....

I don't see how grounding the plastic case or the isolated metal case that a 
standard tractor ignition coil sets in is doing much good.. except perhaps 
emi/rfi interference deadoning, in the situation where the coil outter shell 
material is metal.

In standard kettering ignition systems, and using common ignition coils on a 
points based distribuitor / battery ignition system, I don't see any 
examples yet where anyone shows any thing to the contrary other than the 
ponts are the ground for the primary.. and the inuslated / isolated case 
that houses the coil is nothing more than a container on the standard 
tractor application.

Again.. we are not talking electroninc modules.. or lawnmower engines with 
impulse units..
