Audio Systems: car radio, memory wire, car radio

Question
the radio in my 94 intrepid P/N P4704305 lost power a couple times and now will not come on at all.  No Light No clock.  The main fuse is fine.  Which wires are the voltage so I can check to see if it is getting power or if the problem is internal?  

thanks

Answer
Joe,
On many of these stereos I find defective solder connections on the connectors that are soldered to the main circuit board. The red wire and the white wire are the two 12 volt feeds to the stereo. White wire is the memory wire and the red is 12 volt switched with the key on.
