Before owning my Excursion, I owned a Suburban that went through an alternator about once a year. Luckily I had a lifetime warranty, but it was still a hassle. Fast forward to my Excursion and I just replaced my alternator this morning which is now the third one. Again, I have the lifetime warranty, but it's a pain. This last one lasted two years, but I'm looking for better.
I searched but either answers are limited, or all over the place.
I would like to upgrade my alternator to one that will last, and maybe put out a little more amperage, say in the 140-160 range. I don't want a smaller pulley to where I am changing the belt as well. I just want a quality built unit that will last more than a couple years. I don't want to find myself on the side of the road out in the middle of nowhere with the family on vacation, towing a trailer trying to swap alternators. This is what happened with alternator number two. I plan to get my Edge Insight CTS soon to be able to monitor this, but currently don't own one.
