Hey i had a motor built and am trying to get everything wired back in. From what I can tell i only have 2 alternator wires 1 that plugs in its yellow and blue i think? And 1 thicker red one that gets bolted on. My main question is there's 2 post i can see where it can screw on so am I missing a wire? Wouldnt be a problem but the last owner did his own wiring ☠️. P.s I'm not a mechanic
The 4th connection is for ground: Make sure you have the correct alternator for your car...many Delcos will "work"
