Work truck...Chevy.

What happend to me was my alternator took a dump while driving,my amps dropped,the radio wouldn't work unless at low RPM's,and something else I notice went goofy too,but don't remember. Anyway I went back home,shut the car off and wouldn't try to start,radio and everything worked and my battery was good too at the time. That's when I put the jumpers on the battery and it started. Kind of bypassed something but it worked. Remember,this was in my car.
