Question

I put a new fuse and it blow?

Answer 1

you have a short somewhere. the fuse will keep blowing until you fix the short.

Answer 2

Fuses rarely blow for no reason at all!  Have you checked wiring around accessories that are in this circuit! Turn off ones that you can, and put in right size fuse, and see if it still blows, - then try things on circuit and see which one blows fuse (if more than one in circuit)!

And of course make sure you have the right size fuse there, - smaller ones may not be able to carry power to operate stuff, grossly large ones may cause wiring damage and burning !

Answer 3

make sure you have the correct size

I need more info

Answer 4

the fuse is there to protect the electrical system from a heavy load. if you  replace the fuse and it blows immediately, the load is still there. you could have a short, or a few other problems. you could have mice in the neighborhood that are chewing through wires and that leaves an opening for a short to ground. this would definitely blow a fuse... and frustrate you to heck...

Answer 5

Fuses blow because there is an electrical problem and every fuse will blow until the problem is fixed.  

Answer 6

If the fuse keeps blowing, then you have a short somewhere or you have overloaded the circuit with additional equipment and need to increase the amp rating of the fuse. You didn't specify what your circumstances were.

Answer 7

So does your  " question " You may want to include a little more info , like what you are working on , and what you installed or were working on that blew the fuse.
