how to find a short in my ignition system ,because I keep blowing my ignition f

the best thing u can do is trace wires and see if you have some melted together os shorting against a ground

Ignition or starter circuit? get a schematic to help tracing wires. Power distribution from the fuse that keeps blowing. Does the fuse blow as soon as you replace it or when you turn the key on , or when you try to crank it?
