Got it from Nathan over at Excessive Amperage and used it for 2 weeks now i have to sell the car and i want to get me money from this alt. Its 170a and its 90a idle but will start charging at 900rpm's. My car charged at 14.8v with the system on and do dimming/voltage drops. Still has the sticker on it, no scuffs or marks the alt is MINT. I want $250 shipped for this.
