Charging system symbol illuminated, battery gauge on dash dropped from normal to low, truck turns off after 20 mins or so. What could be the problem?

It could have something to do with it. Check the alt. If it shows good, let me know. I explaine how to perform a draw test. If there is a draw, I'll have you remove one fuse at a time until the draw stops. At that point, we'll know what circuit the problem is coming from.

Let me know.

If you can make it to a parts store, they will check the alt for you. If you can't, here is a how to for checking it yourself. It is very easy to do.

You must have a fuseable link between the alt and the battery that is bad. Check them for continunity.

Not sure what that is. If it is a regular test light, no. If it is self powered, you can, but pay attention if the light is dim. I would recommend an ohm meter that has a continunity setting. That way you can see how much resistance is in the wire.
