Has anyone had a look at there battery junction box. On the left hand side ,there is a sliding panel that says mega fuse. I have two battery junction boxes, only one has 2 terminals for a fuse, if there is s fuse there is it a 125amp or a 175amp. The 125amp fuse does not have large enough holes to fit over the terminals, I don`t have a 175amp fuse to compare, So am at a lose to know what to use if anything.
