Audio Systems: sony cd player wont work, sony cd player, advanced auto parts

Question
Hello,

I have an 85 cherokee and recently as i attempted to start it I lost all electric as if a short had occured in the entire system.  I had full power as a turned the key through ACC, but lost it as i proceeded to start the car.  I turned it off and tried again, but now had no power at all.  The next day, I had power and could start the car but I have lost the use of my stereo (which is why I am asking you this question).  I checked the fuses and they were all still fine, inspected the battery and the connections were still good.  If it helps, I didn't smell anything to perhaps indicate that I had fried some circuitry. Any idea what might have gone wrong here and what I should do next?  Thanks for your help...

Dave


Answer
Dave,

 stop by your local autozone or advanced auto parts store and have one of the salespersons check your battery and charging system .. it sounds like your battery might be work or some other charging system problem .. what has more than likly happend is a surge occured that ran through the system into the head unit .. normally this will trip your fuse in the fuse block but not always.. remove your head unit and check to see if there is any fuse in the back of the unit *sometimes there are and this will blow* if so replace .. also go back to your fuse block and pull each and every fuse out one at a time check ALL fuses not just the radio related ones .. now if none of this pans out test with a test light to make sure you get power to the head unit *probe the wires on your harness with the key on and off * .. if you get power then replace the unit .. if you dont get power .. then you have bigger problems and should take it by a qualified shop for more testing .. hope this helps you out if you need anything else let me know

thanks
