Battery Light Coming On

Around 4000+ RPM my battery light comes on. I've also seen it coming on at lower RPMs sometimes too. I've replaced the serp belt and the alternator and it didn't make a difference.

What else should I look for?

Make sure the ground strap is securely connected along with all other connections (alternator, battery terminals, ect). The battery light indicates a charging issue.

There's a fuse under the hood but since the condition appears to be intermittent I would suspect a loose connection not a blown fuse but it's easy enough to check.
