Most likely the alternator, but could also be that you have a marginal ignition system (e.g. coil). Check the voltage across the battery with the engine running. Should be min 13V. Now turn on your lights + rear window heater. Check voltage again. It will have dropped, but should be min. 12V. -- Grunff
