The voltage spec for the alternator is to be checked at the alternator,
not the battery. The Bosch alternators we have are nominally 14 volts,
plus or minus 1/2 volt.

New regulators are about $20 if you shop around.

Your readings at the battery are well within the expected range. The
farther away from the alternator you measure it the lower the voltage
will be.
