has anyone tried replacing there positive battery terminal connector. i recently bought my saxo and mine is knackered. previuos owner put a jubellee clip over it to hold it down 
i got a universal connector from halfords but the posi on the car doesnt appear to come off. should i look into removing the entire wire and plug?
