as above, the alternator isnt that old, i have good earths, if you blip the throttle the light goes out goes out and stays out, when the light is on its not charging but wen it goes out it is. i took the belt off the alternator and blipped the throttle and the light went off but obviously the battery wasnt charging ?? i have the blue/white wire connected to the alternator and the live. any help would be great......thanks
