Hi On driving a Suzuki Vitara JLX 96 P Reg

Sounds like a clutch problem to me.
So, with the engine off, can you select all gears? If yes, your gearbox is probably OK.
And now with the engine idling, can you select any gears with out crunching? If this is difficult, then try this next test in an area where movement forward or backwards won't be a problem.
With the engine OFF, foot ON the clutch, the handbrake OFF, and in 1st gear, start the car. BE READY TO TURN IT OFF.
If the car moved forward as you cranked the engine, then your clutch is not adjusted properly or has worn out. That is more-than-likely the smell you got before - burnt clutch disc from it slipping.
You can drive it, but every time you want to start off, you'll have to turn the engine off, select 1st then start the engine. Accelerate slowly, making sure the revs don't rise faster that you're speeding up, and change gear by judging engine revs between gears.
Don't keep driving it as it is, as you WILL have gearbox problems if you don't fix the clutch.

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.
