BMW Z4 ALTERNATOR PROBLEM

2005 BMW Z4 • 100,000 miles

BMW Z4 2005 2.5L WILL START WITH A BOOST AND A CHARGE BUT FAILLS TO GO TOO FAR BECAUSE DOES NOT RETAIN THE CHARGE. BATTERY SHOWING 11.5 AND THE ALTERNATOR SHOWING LOW ALSO, BUT I HAVE CHANGED A BRAND NEW BATTERY, OLD BATTERY ALSO SHOWING WAS GOOD, CHANGED THE ALTERNATOR ALSO, CHANGED THE STARTER ALSO. SO WHY DOES NOT RETAIN THE CHARGE, IS THERE A ALTERNATOR RELAY OR STARTER RELAY OR ANY KIND OF FUSES NEED TO BE CHECKED?

There is a fuseable link that could be causing the alternator to not charge the battery. Check that.
