What is the voltmeter reading across the battery when the engine is running? It should be over 13.5Vdc To test the alternator, you really need to have it under load. Run the engine up to about 2000 rpm and turn the lights on, you should see between about 13.7 and 14 volts under these conditions, although up to 14.4 is acceptable without frying the battery. Andy's suggestion of measuring the current drain is a good one, but the clock and the permanently on connection to the radio only consume a few milliamps and a half-decent battery will support this for weeks if not months. Modern car audio systems have two connections, one which is permanently on to support the memory and one which is controlled by the ignition circuit. Matras, for some quirky Gallic reason, have the radio circuit permanently on, and if this is the case with your car, it could be pushing the current consumption up a bit.

I can still distinguish an alternator from a dynamo (generator) My Healey is equiped with a generator. But she has 2 excuses 1) She is from 1963 and the conception is even older 2) It's a British brand (usualy synonym of obsolete conception - Lucas) But ... I have to say that her generator works perfectly, the battery is allways holding the charge, ... And I don't see any reason to update it
