First check your codes. If this is the code your getting P01637, that is the plug right on top of your alternator. Get that replaced. I went through 3 alternators before I realized that was the culprit to my alternator problems. It may look fine, but that one little wire doesn't have much slack. I got mine at the dealer. They will give you one that has three wires, just cut the ones you don't need.............

Check for corrosion too, I'm having a similar problem and my POS+ terminal looks like hell from when the factory battery leaked. Im'a have to replace the whole wiring kit I think.
But I AM getting the p1637
