Review on 💡 Powermaster 48237 High-Amp Alternator: Optimize Your Power Output by Ronnie Polk

Because of this alternator, my truck constantly had a code P1635 indicating an error with the ECM readings. I replaced everything I could think of and it never went away (until I replaced this device with another brand). It would also say that the battery will not charge when the truck is started, but will quickly stop showing the error and return to normal. Eventually the whole block died while driving, the voltage dropped at a slow but constant rate until the whole car died overnight. I had to have it towed, replaced with a new generator in the hotel car park and everything was back to normal before unfortunately installing that generator. I do not recommend this product, only problems.
