I had an issue with my battery on this truck. I was swapping tail lights on the flatbed. I ran the battery dead and had to jump start it. This is an old farm truck but the radio was working. I checked the fuse and when I pull the fuse the clock goes dark. Put the fuse back in the clock comes back but no radio. Am I missing a fuse somewhere? I pulled fuse 17 on the side dash panel. Is there a second fuse I could be missing? It is the Delco Electronics radio with the CD player attached underneath it. Thanks in advance.
