I have not done it in years but some part stores use to see alt and starter kits. The alt. kits had a new bearing, diodes, brushes and regulator I think for a fraction of the cost and was not hard to do. Does anybody know it they still sell these kits. I know you can still have bad windings but you can test for that before you purchase the kit.

When I first got my truck, I was changing alternators regularly. Now I don't any more, and it's because of one or two things, don't know which.
1. I quit using new alternators from an electrical repair shop (probably made by a honest and hard working 9 year old in China) and put a Ford rebuild in.
2. I found bared wires on the alt harness by accident when changing my egr valve, I had a screwdriver or something metal trying to get the valve out and seen sparks when I touched the wires. It was (possibly) shorting on the intake manifold.

thats the best spot there canbe some voltage drop if you get the reading eleswhere But should be minimal at that

You would need to unhook the batterys from each other if your load testing them

Well I just got done changing my alternator. Bought a new one from Auto Zone (135 amp). I found a link somewhere in here for "the Power Stroke Tool" and it was by far the best $30 I've spent in a while. It took me 20 minutes with a headlamp and in the cold weather to figure out where to get it hooked in and the rest was as easy as the video on their website. www.powerstoketool.com.

I guess just pulling on the serpentine belt works well if you know what you're up against, but this made the whole thing a piece of cake.
