Alternator has been refurbished but I never used it. It is very clean, looks brand new. Single pulley but not sure of what amperage it was rebuilt too (37-46-60). Local auto parts stores only test internally regulated alternators. My zip is 20685 and I will only charge actually USPS charges to your zip code area if you purchase item. FYI- it weighs approx. 15 lbs. in the box. I only ship to the lower 48 states $80.00 + actual shipping fee to your address I accept PayPal, checks and money orders. I ship when a check or MO clears my bank.
