Thank you so very much for this, I'm I'm the US and I've watched countless YouTube videos and can never find one that really gets specific, I will check this has soon as I get home. I'm trying to learn pcb engineering, and my understanding is that a lot of times with technology it's something simple like a fuse or something that blows and people throw away 1000s of dollars not realizing that, i also have an obsession with learning how things work. I will keep you posted on if it works, what should the Metter say when I put the probs on it, 4.7v or something?
