[AT] question on use of resistor on coil

[Dean VP]

Walt:

I unfortunately have to disagree with you that 12 volts won't hurt the coil.
The coil will run hotter than it was designed to and will eventually fail.
Heat is the greatest enemy of electrical products. Bypassing the resistor
for starting is only momentary. But running it at 12 volts continuously will
eventually cause the coil to fail.

The reason for the ballast resister is to keep  the higher voltage (12) from

burning the points.  It won't hurt the  coil.  the reason you don;t see them

in some early GMC vehicles is because  they had a resister wire from the key

switch to the coil. It was very  stiff.  I have seen people who didn't know
this 
that would replace it with  a standard wire and wonder why they kept buring 
up the points. Of course in the  days before electronic ignitions we were
lucky 
to get 10,000 miles out a set of  points and spark plugs. I think I changed 
them on my Saab Sonett more than I did  the oil. 
My 97 ford Ranger says to tune it up when it reaches 100,000  miles.
