Most likely your alternator is not at fault.
There is a short to ground on the circuit that blows the fuse..
DO NOT...I repeat DO NOT install a larger fuse or something to bypass the fuse.
You will need to trace the harness and look for the affected wires.

Running jumper cables is not going to help anything...you are just wasting your time.
If you want to diagnos and repair this yourself, you will need a good service manual with wiring diagrams.
What is the name of the fuse that is blowing? Is it the guages/idle fuse?
if so there are about 10 componants that are powered by this fuse.
This is a power wire that is shorted to ground..either by the insulation being chaffed somewhere in the harness or a componant that is drawing more amps than the circuit is rated for.
