I wired up some axuliry lights and blew somthing so know my truck wont start. Turn the key and i hear my new relay click then i lose all power. Had the battire tested and its good. The fuse block under the hood i pulled the fuses in the front and they look and ohm out so i assume they are good. My question is what to look for to fix this and how to check the power diode i belive it is called.
