I just bought a new battery and it died because my alternator isn't working. I think i have the wires wrong. I have a thick red wire and a thin green and yellow wire going to the back of it. I know where the red goes and the green and yellow are side by side and plug into 2 male prongs but I dont know if the green goes on the left or right prong?? The orientation would be looking at the back of the alternator while holding it with the 2 male prongs at 12:00.
