Hi, got a problem with my headlights. Side lights come on as should but thats all ive got. Not bulbs as checked them and as far as i can tell the wires are in position. Full beams come on if i flash my lights. any ideas as to what the problem could be. also alternator has started to produce backflow so flattens battery when engine off. any chance these 2 are related?? Not sure if they started at the same time but noticed them within a day or 2 of each other. cheers
