I did a search and cant find the answer. Last night i left my lights on and the battery went dead, so today i jumped it and started it and drove it home. On the way home the tach worked but the speedo never moved and the radio wont play anything. Its an aftermarket headunit with flip out screen. I can get the screen to open and close and all the buttons work but the screen is very faint and it wont play a cd. I checked all the fuses under the hood and down by the pedals. I have power to my seat, and the key fob works. I have a speed cal and both power outlets seem to be working. Anyone have ne ideas..I didn't hit any bumps or nething to make it short out, just jumped it this smorning and things started messing up. Any ideas?
