so on my 1980 i have never had a problem starting it and the battery always had some juice. will i was driving down to the store and when i hit the blinker the stero died untill the blinker went off. I thought how wierd maybe wiring or something. then when i came out to start it to leave NOTHING! no jucie. it would crank but nothing. so i get a jump start and head on home.. on the way the truck starts to sputter like it is not getting any fuel( i have an electric fuel pump) but it makes it home just in time before she dies. SO i think altinater has to be bad and not charging anything. so i replace it and it still does the same thing. So i am going to test the battery and make sure that is not it... but i don't think it is... anyone out there have some ideas to throw at me??? any help would be great RED
