So, let me preface this by saying, I was a dingus. I was an idiot. I did this, and I knew better..
So, the other day my wife's car was dead(the Taurus) I went to jump it, and, with the cables covering the makings and the posts sprayed with the corrosion stuff, that's RED, I connected the positive to the negative and the negative to the head bolt tab. When that didn't work, I moved the ground to the battery (positive) and well, smoke, sparks, etc. Now. Radio is dead(climate still works, manual controls) can't turn it on, no clock etc. That I noticed right away, along with the abs light. Fast forward to today(the next day) I notice the speedo isn't working. I hear the speedo goes through the radio fuse? Does it possibly go through the radio as well? I checked the fuses under the hood, all look fine.
A new radio off eBay is 150 bucks. New factory old stock, in box. The radio was having problems before, ejecting tapes, so it kinda needed replacing anyway. I have the ax4n trans, did a fluid flush(pan drop) a few weeks ago. I don't believe that to be the culprit.
Any other ideas?
