Matt you should be getting 14 V when it is running. Time to change out the alternator.

That battery light is very stubborn. Definitely should be 14+.

I went with a NEW auto zone alternator and havent had a problem since. Ive heard some of the remans dont last too long but you still get a good warranty regardless.

Tristan got that right. Sometimes they work sometimes they don't. Get a new alt and not a reman. If you want a higher output and can wait a few days DB has the best deals

You won't be dissapointed. You may have to grind a little bit off the crossmember for the starter though. Some have to some don't.

Remember that if you haven't changed your batteries in a while that weak batteries means over worked started and in some cases alternator.

Maintain your batteries

And BTW, umm, WOW to the 200amp, I didn't know these things could produce that much juice!!! What is the stock amperage? 120?

Stock amperage is 110A for the alternator. And you should see 14.4VDC (definitely 14+) when the truck is running at high idle.
