RE: [split] 1996 Jeep Cherokee  problems
A 30 amp fuse is pretty heafty so you probably have a direct short someplace. I'd do a visual of the wiring harness and see if it's got a bare spot from rubbing on the engine, trans, inner fender, etc. Also look carefully anywhere there may have been previous body damage because it may have not been properly secured or could be a poor repair waiting to haunt you.

BTW, you said it blows when you try to start the car, which I take to mean the actual cranking process and not just "key on" while waiting to crank. Follow the harness toward the starter and see if anything has signs of chaffing down there. You can also try disconnecting the smaller wire at the starter to see if the problem persists. If it goes away you may have a shorted starter soleniod.

As a diagnostic aid you can purchase a 30 amp circuit breaker to substitute in the fuse block and that will keep you from having to buy a dozen fuses (or more) while you do further testing.

Good luck
