Hi, do I need a voltage regulator when using a 3-wire alternator? Or is everything directly connected, like coil and so on? I just need quick basic information as the wiring in my car seems a bit odd. The alternator is on the photo, I can upload more later. There is something that should be a voltage regulator in the car. But as I look on wiring diagrams online it might be that I don't need a regulator?! Thanks for help!
