Alright guys, I bought a new Sony head unit for my 89 YJ because I thought the stock head unit was done. Well after I wired the new on in I turned the key and nothing happen. So I look at the acc fuse and it is blown and I replaced it. Turned the key to the on position and it worked! Well once I went to go for a drive I got not7 feet out of my driveway before it went out again! I don'tknow what's up! I looked for any bare wires(taped em) or loose wires and nothing! Help!
