Replaced NSS now has code P1594

SO we replaced the NSS on my jeep, switch threw a ton of codes. We since figured out it was a rock causeing a grounding issue. We got 7 of the 10 codes cleared. Put on a new alternator (even though it was replaced a month ago) and we are still having over voltage issues.....Any thoughts or ideas???
