Yes i did check my grounds and they look fine. I dont really want to swap alternator unless i have to. Its not hard to do but I have a hard time adjusting the belt and its about 100 dollars. You mentioned wires (blue and white) are those on the alternator itself or internal? Or do you believe my best bet is to just replace it?
You could replace it and drive for a few hours to check if the problem is resolved. 100 bucks can be returned if you only use it for a short period and keep it clean. So just replace, check for probe, return if not rectified.
