I HAVE REPLACED MY BATTERY AND ALTERNATOR AND BOTH TEST GOOD. MY BATTERY LIGHT KEEPS COMINAND THEN MY BATTERY GOES DEAD WITHIN 20 MINUTES. IF I MOVE MY (RELAY BOX?) AROUND THEN TE BATTERY LIGHT GOES OFF AND THE TRUCK RUN FINE. DO I HAVE A ELECTRCAL PROBLEM OR SHOULD I REPLACE THE (RELAY BOX?) IM NOT SURE IF THATS WHAT IT IS CALLED BUT IT SITS UNDER THE HOOD ON THE DRIVER SIDE AND IT'S A BLACK BOX.

THANKS FOR YOUR HELP,

WHYEETHIA

If there is fuse's in there then that would be your under hood fuse box.Sound's like you have a loose wire that probably feed's the power to your alternator.That run's from that fuse box to the alternator.The fuse for the alternator is in the battery junction box it is fuse number 11 it's a 20 amp fuse when it's not charging and the light is on see if that fuse looses power you can use a test light to test that.
