Re: Problem after install new dizzy cap

The main feed wire is 10AWG red wire running from the Junction block on the firewall to the starter. The burnt Fusible link was 14AWG right at the starter.

You'll need
a solder gun,
electronics wire flux,
electronics grade rosin core solder,
14AWG 3/8"& 10AWG 1/4" uninsulated ring terminals,
approximately 6" of 14AWG fusible link wire (should be the same length as the burnt link),
and several feet of Red 10AWG primary wire.

The studs on the starter and junction block are made of copper, not steel, so tighten them carefully.

This is a really good how-to writeup on building fusible links.

If the Purple start wire is damaged I'd solder and heatshrink a repair. A replacement ring terminal should fit a SAE #8 stud and the Purple wire is 12AWG.

I'll probably get the '75 wiring diagrams posted up this evening.
