I'll be brief

Blew mains fuse in engine bay. Fuse wouldn't come out. It just cracked and s**t.

There is a screw on the inside of the fuse compartment, but good luck undo'ing it. How do you replace this fuse?

Fuse 2 in your ba falcon manual.

Mines a BA Falcon XR6 MKII Auto if that helps

Cheers

PS: It doesn't just come out I tried. I even tried the ABS next to it and it cracked and broke the same :S

NEED HELP ASAP SO I CAN GET THE CAR RUNNING FOR TOMORROW MORNING!!!!

the main fuse is held in by two bolts, you need to undo them first.
As to why its blown - most definately a short circuit somewhere - what did you last do to the car before it blew?

its a easy fix as already said by 66 coupe but judgiung from the amp fuse wires you were installing you may have done something wrong so just recheck what you have already done

all fixed thanks boys (maybe a girl)
