i'm working on getting my engine all rewired. i've pushed through the forum threads on alternator wiring, but either i don't understand what i'm reading or i don't understand what two of the screws on the back of alternator are for or both. so a picture is worth a thousand words. attached is the back of my alternator. i can identify the B+ (goes to battery), the AC tap (goes to tachometer). but there are three other screws, one just above the AC tap and 2 about 12o'clock and 2 about 3o'clock. one of the screws at 12 and 3 clearly hold the case together (same head pattern as the two in the center), but what are the other two for at 12 and 3. i think ones a ground and the others a sense wire, but i'd rather not guess
assuming one of the bolts is for a negative wire back to the batteries what gauge is that supposed to be. clearly it's not the #2 i'm using for the B+
