Hello good morning billy58 look I did not measure them, because I do not know how to check them, but it does not light any I would like to know what voltage goes out for each LED strip and know if it is delivering the correct voltage, and thanks for your time greetings

Something that can be useful for you is a LED test, I send you a diagram of the one we use, with good results. You can check each led separately and also the complete strip. greetings everyone.

Mr. Javier. It is good news to know that he could solve it. Congratulations !!! .- As for the meter is one of the best work, especially because you can check LEDs separately. greetings everyone.
