How do you change the 60 amp fuse on my suzuki vitara 1.6 jlx 1997

If this is one of the big block fuses under the bonnet, then if it doesn't pull out by hand then it probably bolted in. You'll have to first disconnect the battery and then unscrew the fuse box from the engine bay. You'll then be able to see the 10mm headed bolts that are holding it in underneath.
