Alternator Mods

Hey there,

I am really loving the site, btw! Some really great info on here and everyone seems to be pretty cool.

My question is on alternators. I am reading about the drag it puts on the engine, people wating to upgrade to LED lighting, installing cut off switches and deep cell batteries, etc. Now I am a mechanical novice when it comes to autos. I understand the basics of how things work but I am by no means an expert. I know that the alt pulls power from the engine just like the AC does when it kicks on. Does the alt drag more on the engine with each extra amp it produces? If so, if you could turn it off and let it "free wheel" any guess as to what the increase in FE would be?
