Question on fuse

[tmason]

I have a inline fuse that connects to the postive battery side and goes to relay on fire wall. The fuse has been broke for a long and I discovered it when I removed the battery.Does anyone know what this is for? Thanks in advance,Tim

Probably an aftermarket stereo/amp installation power wire.

It looks like a Factory install because the positive cable has a place to bolt the connector to and it run into the bottom of the relay? I could forward a photo,it wouldn't load on to the site?

If you have a/c, or an automatic, it could be the fan relay fuse. There are several variations on this circuit. The blue books show three configs. All use a flying fuse directly from the battery.

Thanks vraned
I have both but I don't use the a/c and I'm replacing the a/t.If someone has one and they want to sell it let me know. Thanks Tim
