Ballast Resistor-Help

I had to replace my coil and the new one requirers an external resistor. My 1969 GMC does not have a visible resistor and my wiring drawing do not show a resistor. Do these trucks have a resistive wire and not the resistor?

Yes. The stock wiring has a resister wire that feeds the coil.

May those who love us, love us, any of those who do not love us, may God turn their hearts.
And if God is unable to turn their hearts, may he turn their ankles so we may know them by their limping.

A man who works with his hands is a laborer; a man who works with his hands and his brain is a craftsman; but a man who works with his hands and his brain and his heart is an artist.

Yes, it's in the wire going to the + side of the coil.

Should only get about 9V on the +side if I remember right...

there are no ballasts or resistors on GM vehicles, the wire itself is not copper if you look at it, the material of the feed wire to the coil is the primary resistance in the circuit, its between 1 and 2 ohms

My '57 Chevy has a ballast resistor on it.
