Did the test for failing alternator diode as per Google search- ie set multimeter to AC voltage and run the engine - if the diodes are OK there should be no AC going from the alternator into the battery or so I am given to understand - well am getting a reading of 30 AC volts which seems to point to diode failure which could explain battery drain

Yet RAC man and his test says the alternator is fine.
