using a test light or voltmeter do you have power on both sides of the fuse?
assuming you have power on both sides of the fuse, using the test light or voltmeter tracing the wire from the mega fuse to the fuse box, do you have power at the end of that cable?
if you dont have power than that cable is fried.
