It will be going to your alternator and is there to prevent a fire (should the worst happen....)

I wouldn't advise removing it, but you could replace it with a different type of fusible link. Wink

Yes. Fuses are not installed to protect equipment - they're there to protect the wires. If a short circuit happens, and large currents flow, wires can heat to the point that they permanently damage their insulation and, worst case, catch fire. Remember, a car battery can generate enough current to weld.

A fuse/fusible link/breaker is installed to interrupt the current before the wire is damaged - or anything else. Car manufacturers don't spend a cent if they don't have to - these links aren't installed because they look good.

When I rewired the alternator on my old Feroza I simply reused the fusible link section. You could do that unless it's not in good nick?

You could replace it with a good quality fuse but the wire link might behave like a "slow blow" fuse- whereas most heavy duty auto fuses are of the "fast blow" type.

If you did replace it something like this would be a good option

You can then select various fuses to suit. I'd be thinking of at least 100-> 150Amp for your alternator?

thanx murcod.yeh i think i will do away with the original coz it doesnt look the best.the projecta terminal looks good,would look neat to.i had a look at the fusible link today and theres 4 cables goin to it.the main one is about 2 gauge wich i say would be going to the altenator but i dont think its running through the fusible link coz its connected to the positive by its own lug if you know what i mean.then theres one that is about 8 gauge,then two more smaller than this wich would probaly be about 6 gauge,they i think are running through the fusible link. i had a look in the gregorys today and from the diagrams it looked like that the fusible link that im talking about is for the power windows,sunroof,mirrors and rear door lock wich i havnt got.dunno if this makes sense.regards.
