Fuse checker?

[DJWilson]

Hi

i wanted a fuse checker thing. i mean you can put two bits on the end of the fuse and it shows how much life is left. i think it is vitual espically when it coems to your amp.

p.s you knwo where i can get one?

thanks.

Err.. fuses don't have a life... they either work or they don't. You just need a multimeter to check if its dead or not.

or simpler & cheaper, an electrical screwdriver with inbuilt LED for checking continuity.

Or just buy a new one, rather than buying an instrument to test something that cost pence.

there are situations when you want to be able to test the continuity of a fuse, rather than throwing it away and replacing it "in case" it is dead

Bit of a strange one, this. I have always been under the impression that a fuse will blow when a current larger than it is designed to take is passed through it, regardless of anything else. I suppose it may be technically possible that a fuse weakens over a very long period of time, so it's not that ridiculous a notion.

No, I suppose, not that ridiculous as a current going through a wire is effectively slowly wearing it out (otherwise there would be no friction and we would have discovered the utopic perfect superconductor!).

The thing is, I would expect it would take many, many years to wear out a fuse on that basis. Certainly more years than the rest of the amp would last.

Perhaps a testing screwdriver is the answer as at least it has another use to make it of real value.

im askin because at school the caretaker had one for the lights and laptops etc...

and it shows how much current is left init.

i would to have one because then i no weather to change the fuse in my amp or cd player before a gig. just to be on the safe side and not to waste any fuses for no reason.

and it shows how much current is left init.

As much as you pass through it. Fuses don't hold a current, they merely let one pass through (or not if it's too high)

A fuse is simply a short piece of wire.

I really wouldn't worry about checking them though.

I've never had a fuse blow in 25 years on the road.

In most cases, the fuses will last longer than the equipment they are in.
