Review on 💡 Optimized Powermaster 57759 Auto Alternator by Ron Coleman

Put this in my 1991 Bronco. I had big speakers and when the bass played the lights dimmed. With the addition of this alternator and Optima Blue Top battery, this problem is gone and my system is able to perform to its full potential. A few reasons I didn't give it 5 stars is because it didn't quite fit. Of the two screws holding it to the bracket, one came out and the other unscrewed slightly. Enough that I couldn't secure it with the second screw. It's also a bit expensive. But it works as advertised and comes with easy-to-follow instructions. I'm probably a 6 out of 10 for being user friendly and had no trouble installing it myself.
