You need to start with the main fuse located on the fire wall. Follow the positive battery cable to the fire wall and you will see it go in to a small junction box where is branches off. Inside that small junction box is a large 125 amp fuse. This fuse is most likely the only one that is bad. You can use a volt meter or a test light to make sure there is power on both sides of the fuse. If there is no power on one side, the fuse is bad.
