Charging Voltage

Does anybody know what the manufactures specification is for the charging voltage from the alternator.
My mini runs at about 14.6 volts with no load and about 13.8 volts with electrics fully loaded.
These readings are taken at about 1500 rpm.
Cheers.

Normal running voltage across the battery terminals is 13.5 to 14.5 depending on load. A condition higher than 14.8V may indicate a regulator fault.
Battery voltage is around 12.6V with igniton off.

Within any error on your meter, yours sounds OK
