Re: Blowing Fuse on Dash HELP HELP
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.

Re: Short
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.
