right guys ive bought 4ltr range rover vogue se(1992)last weekend and well happy with it but ive got a promlem with it and in need of some advice asap.when im driving it sometimes the battery type symbol light comes on and goes off sometimes stays on for a short while but then could stay off for a long time lol would anyone know what could cause this,also i had a look at the battery yesterday and its lowish on water in it so could that be my fault as in not much to charge inside it or not?
