Thank you for the rapid response. I understand what you are saying. If you do not put a switch between the + wire and the radio + wire, the radio will be ON all the time. The other wire you refer to should be connected "hot" all the time to maintain the radio pre-sets. My problem is that the stereo will only power up when I use a meter to test the 12vdc on the radio. I do not have a ON/OFF power switch for the stereo connected yet. The 12vdc is connected straight to the stereo and not through a switch. I am assuming the 12vdc "+" and 12vdc"-" wires are coming from the 12vdc fuse block in the power panel. Maybe this does not work and have to take the "-" wire from the stereo and ground it to the frame?
This is why I was asking if anyone out there had experienced the same problem.
