Defective 250 amp alternator UPDATE: Have to say they made this right. I was contacted by a rep and they replaced the item and paid for shipping to return the defective alternator. I couldn't be more pleased with the customer service! INTEGRITY!! I was given a 250 amp alternator for my birthday approx. 1 1/2 years ago. I wasn't able to install it until 8 months ago because I didn't have time to upgrade wiring. It died this week. $550 + for something that didn't last very long. I do not recommend this product. It's inferior.
