Have you checked the earth straps from the engine to the inner wing and in the boot from the boot floor to the battery? Not sure about the mk 1 but on later models they are a braided metal strap that are prone to breaking down over time (particularly if moved/disturbed). If they are in a poor condition they will result in ineffective charging, dispite replacement of the battery and alternator. If they are at all worn then I would replace them to at least rule them out as the culprit, some people even replace them with a more modern plastic coated earth strap, to prevent a reoccurance.
