Replaced with oem alternator that start to fail. Option was to rebuild oem alternator with rebuilt kit by myself but this affordable price made it feasible to just replace it. So far the output is stable 14.5v and working well. No up and down of voltage, with or without load. There's a little tab that stuck out on connecting ring part but I just clipped off that stuck out part so it fitted well.
I am happy with this alternator and it's price.
