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.

Easy to find the part Easy to find the part, really should not have went out in the first place. But glad they had it. It was the on an off valve for the water filter. Was leaking. Poor construction is all I can think, plastic ball valve. Got 3 years out the older one. The price you pay for this stuff should be made unbeatable.
