Cleaning out my truck this past weekend, I ran the battery down playing music. The truck didnt have quite enough juice to start, so I charged the battery with my portable battery charger for 5 seconds and it started right up.

Now the problem, the cd/radio doesnt work. I checked the fuse and it was fine but i changed it anyway.

Where do I go next?

 

once the battery is fully charged, try unhooking it (the positive wire) for a few minutes and then hook it back up.

hopefully this will reset the radio!
