Alternator wiring...please help
 

My problem is my alternator works but isn't charging the battery and I don't thing it is wired correctly due to the PO swapping the diesel. For a 454....does anyone have an alternator wiring diagram or clear pictures that show how it is hooked up? Anything will help this is my daily driver so I need to fix it...thanks in advance

What year is the truck? What type of alternator? You can find wiring diagrams on www.autozone.com under their maintenance section. You have to sign up for their website.

Click on the image and it gets bigger (and more legible). When it enlarges, right click and download. You should be able to see it pretty good.
