I try to put my fuse into the box and everytime I do it blows it controls the stereo so i have to have it wired off the battery Could it be the ground that makes it so the fuse keeps blowing????????

 

You have a short in the system.

 

A fuse blows from a wire shorted to ground or too much current running through it.

 

How can i test for it or find it

 

well I would be looking at the wiring for anything aftermarket in the system, such as a radio or the like.

99% of the time where there is a problem it is from something that someone put into the car incorrectly.

Who put in the radio?

 

I had my brother install because he is good with electronics and it works for a while now it stopped working and the stock stereo won't even work So now I have it wired from the battery and its on a switch but i wan't to get that fixed

 

well it sounds like your brother really is not good with electronics and that you need to have your radio installed by a professional installer.

There is probably a pinched or shorted wire behind the radio, toss that in with blown fuse and your radio won't work.

 

alright thats what I kinda figured Thanks
