If I oversize my alternator, say with like a 180 amp late model GM unit, will I screw up my battery? I am planning on adding electric fans, a Vintage Air unit, and an electric water pump and fuel pump. I'd like to have the extra amperage, but I don't want to cook my battery. Anyone had any experience with this?

dont think it would, but what do i know, i only use a 50 amp delco rebuild.

That's what the regulator is for. To keep things from getting cooked.
Internal or external, they do the same thing. Make sure your alternator has a good internal regulator.

Excellent - thanks guys. I figured as much, but I remember reading on here about someone who was having troubles with their battery bubbling over because it was being overcharged.

I definitely need some more juice if I'm going to be running all the electric stuff I want to run, and I figure I ought to throw it in now while I'm still trimming out the engine compartment. Just didn't want to cook anything in the process.
