so i went out wheeling at one of the local mountains, all went good so i started heading back. as i got to my friends house afterwards i shut the truck off. when i went to start it again i got nothing, i didnt get any accesories come on either such as stereo clock etc. thinking it was a dead battery, i tried jump starting it off of my friends tacoma, still got nothing. thinking its either a loose electrical connection or a blown fuse. HELP ME
