Review on 🔋 Optimize Alternator Performance with OBDMONSTER Analyzer: Advanced Charging Solutions by Loren Slama

It's a little tricky to use and easy to wire up, but you should read the section on which lights mean what as they almost conflict when illuminated by multiple lights in the same test section. If they only turn on one light per test section and turn on other lights that light up in each section separately as a new test section, it would be better and easier to use. I believe one was solid and another flashed in the same section, making it difficult to tell what was going on in this test.
