I'm wiring up a 2J alt in my boat, Can someone please tell me where the 3 wires go??, I had an auto elec tell me months ago, but aaaaah I forget now, I know 1 goes to the charge light( does the other side of the charge light go to ing?), and one to the ingition, and one to the battery I think......... anyway some help would be great, save me pulling it out and takin it to the auto elecs again....... and getting a smack over the head for not writing it down
