reistors or resistor wire drop voltage

Did you check it with the points closed?
Open points don't draw any current
no current = no voltage drop
The pink wire is a resister wire

As stated, pink wire coming from ignition switch is resister wire. You should have about 8 volts going to the coil, unless someone has replaced it with a coil with internal resistance or the resister wire has broken down.

what length of resistive wire would i use in order to get to 8 or9v at my coil. i ask because i had to rewire some of my truck and didnt think about there being any special wire

mount it someplace cool firewall or fender
adjust for around 9 volts with the points closed
