Today I installed my kenwood excelon headunit onto my other car. At first i got everything together fine. It played cd's and everything fine. When i stuffed the wires back to fit the cd player in, the power wire (I think) from the headunit got pulled too hard and it came lose and then one end of the wire fell and touch the metal of the headunit. Right after it touched the metal part i heard a little shock and then the head unit turned off. After that the head unit didnt turn back on anymore. I'm assuming that this is called a "short circuit." is it possible to fix a short? I thought that if a short happened it would have just blown the fuse on the HU or somethin but when i checked the HU, the fuse was fine. Can anyone help me? thanks
