or would it possibly be something else, i have owned the car for 2 1/2 years & have changed neither battery or alternator.
thanks for any help/advice, gordon.
do you own or have access to a multimeter? you could check the output voltage of the alternator. I would recommend taking your car to halfords or somewhere that does batteries and could load test it to check the condition of it, it should be free of charge in the hope that they can sell you a battery if it fails.
