ok, how can it not charge? all it is is a thick wire coming from the live on the battery to the starter motor, and from the starter motor to the alternator... it earths throught the engine and theres a thin wire going to the warning light,, if its not guna charge the light will come on brighter! but it aint, its as though its not charging fast enuf!!!
but yeah theres deffo summat draining it! when the battery is fully charged it will take about 3 days of been stood to go flat.. but when driving it seems as though its only trickle charging it and not charging it fast enuf..

so this seems like symptoms of a fucked alternator,, am i right??
