03 s type r. I disconnected the batt. Re connected and now the batt light comes on the dash. Batt. Is charging 14 v. Batt. Is fully charged and connections are very clean. New to the forum. Love the car very low mi. Thanx ahead of time.

 

Did you change the alternator? If so, common issue with aftermarket alternators. You'll need to source an original Jag alternator.

 

No , original alternator. Read several ways to rest CCU one was to disconnect batt. This is when it occurred.
