fuse box

Ok I looked around and did not find a whole lot. All I know is that it used to work and then my brother and someone else were messing with the cluster they touched something on it and it stopped working and it sits at empty. My brother was going to replace the sending unit but the one he got looked different then the one in it so he didn't. So I did what you said and the gauge moved up about a notch and that was it.
