Once running that circuit disconnects and ithe. Oil is now powered thru the resistor circuit which drops the voltage to about 9 volts, so you don’t burn out you points.
When the industry went to 12 volt systems, this is the way they were installed by the factory.
Bottom line is I get full voltage to help start the truck then reduced voltage to help save the points.
