Surging noise while driving
Gentlemen,
I have a 45 min drive to work every day, all highway. Lately on the way home in the afternoon I have been experiencing a surging noise that seems to just happen while I'm doing hwy speeds. It sounds to me like the fan is tuning on and off. Is that possible? It comes on for a few min. And then off again. I have new icp ipr cps. New oil and filter and fuel filter.
Also I'm still having a battery light on and off issue while I'm driving. Is possible the two issues are connected. I plane on doing extensive search for a bad wire this weekend. Batteries and alternator have checked out and are fairly new. Any advise is greatly appreciated.

Your location says "hondo" and if it is hot in "hondo" it is entirely possible that the fan it coming on and going off based on the ambient and road surface temperature. My fan typically does not come on unless it is hot out and I am towing, but each truck has its own personality.
Someone with a lot more sage type advice will be along shortly, this is just my opinion.

Yes, Hondo. Gods country please don't drive through it like hell, as the sign reads.
Forgive my ignorance, i assumed the fan was always on while driving. Does it engage on and off depending on temps?

If you have a way of monitoring your oil temp you can kinda get an idea of the temps when you are experiencing the noise/surge. The fan clutch is filled with a gear oil that will allow the fan to engage more as temperature increases. When towing during the summer up bigger grades it can fully engage and sound like a mini hurricane under the hood.
