Chevrolet Repair: suburban, chevy suburban, alternater

Question
hi, i have a 03 chevy suburban and the battery light blinks on/off and say the battery is not charging and just had a new alternater put in. Do anyone know what this problem can be

Answer
Hi rob... check the alt and battery connections...check the system with a volt meter...should be 14v at the battery or better... wiggle the connections and see if maybe one is loose...light blinking suggests that it is losing connection somewhere in the circut... hope this helps
