So My OBD2 wasn't working when my buddy tried hooking his Diablo up to it. I decided to take it to Autozone and see if they could read any codes or if they're little hand held would even register on it. Well I get there and it didn't even read so he said I had a blown fuse for my OBD2, said ok let's replace it. Well we found it, replaced it. Blew as soon as we put it in. Unplugged the battery, put another one in, hooked up the battery and tried again, as soon as we hooked up the battery it blew another fuse...he gave me the rest of the fuses for free and said take it to an electrician to find a shorted ground wire...is he right?
