Very good Alternator - honestly, I think it is new
Solid alternator — works exactly as expected. My original unit needed a new rectifier, and while I had it apart I planned to replace the brushes and bearings as well. Unfortunately, the rectifier was backordered, so I picked up this alternator from the lower‑cost list as a stopgap. When it arrived, it looked very good, in fact it looked new. I put it on my Weidenhaus Alternator test bench spun it up and applied the carbon pile producing 112 Amps. Solid, good enough. (Yea, yea, I know - not everyone has a test bench. My family used to own an Auto Electric shop. I have a lot of these cool antiques in my barn. I even have an 8-cylinder Magneto Tester, in fact all of the magneto tools.) It’s been a reliable replacement, and I was able to keep the original core. I’ve since rebuilt that unit and set it aside for future use. For the price, this alternator was a smart solution that kept my truck running with minimal downtime. ... show more

Works like it should
A lot of people complained about the hit and miss quality of aftermarket alternators for my 96 Ram 2500 with 5.9 Cummins. I figured i would roll the dice as a "factory" alternator was $300 plus dollars . . . and i just couldn't justify that cost on a 250k mile truck. Anyway, shipping was fast, packaging was ok . . . the plastic guard for the charging lug on the alternator was broken . . . this has no impact in performance so I installed it anyway. I changed the tensioner and belt at the same time. The whole project took about an hour. Started the truck and the alternator was charging and I was holding a consistent 14V. Time will tell how it holds up over the miles, but currently, I am a happy camper. I am keeping my factory alternator and rebuilding it this winter as I have time and will keep that in the tool box as a backup . .. Just in case. ... show more
