hello er this is life Hagler I have just Auto some systems at Aliexpress and our team they all are fake so I going to show how to test if the transistor are real one or the fake one so if you look at the schematic here ever made something that can easily check the transistors so this will be the transistor in these case I have a moose fat consists oh but that will be the same in that somatic so I add 32 volt in to a system I wanted regulator and I have some load I can switch on since its valve volt out I can switch in 12 ohms resistors one by one many so I get at one amps increase every time I switch one per you can look at this one I made a simple way to switch on this resistor each resistor is 25 watts so that should be enough and this somatic I am built in this box just to make it easy to change different consistence I also made one for testing the NPN transistors but now I'm going to show how to test PNP or moose fat PNP in this case they're going to be a moose fat okay now we are ready for testing an original moose fat consists or it will be instead of this PNP transistor huh let's uh ERF ninety five forty we going to test this is the voltage over the transistor this is that current going through it say our now and this is the voltage going out to this load transistor self I can put in one by one to increase approximately one amps each the system uh put in in parallel okay let me start the test first one amps no problem two amps or 1.8 mm almost three four five almost and 5.5 there now I need to switch off was no I think it's going to get very hot the cooling hair is not to be best one so I need to be a quick test but it survived almost to 5 amps five multiplied with twenty should be about hundred watts of power let me take one more test one two three four five six seven persistence six point two and three shop not only tested 26.2 amps and that would be a good test for decent system I know that is all a general I don't want to blow it up or something so I just tested with with this to show you okay done we got a test one of the transistor wanna see from aliexpress I think everyone is fake but I want to show you that the amount on the one of them have no amps now and we start the tests and see when it it will not blow off but you see that the voltage have will be the 12 volt regulate it will be a full power off it's a short adventure so it will be yeah like a short circuit to them okay one amps no problem two amps no problem three amps no problem there something happen yeah mosey instead of 12 volt out we have told you what out that means this is shorted out is completely shorted have this is the voltage of transistor almost ever and even if I switch off you have 30 on 12 ohm and that will be 2.5 amps so this bike with this form so whatever I had - we drove okay I'm going to test one more amperage over the a lot through transistor voltage Ottomans transistor and voltage out that should be 12 volts table all the time so we test how many amps it will go before bike it should take 10 amps so so it's a very bad quality actually but are we going to test how much it will take before bike 1 amps ok almost - ok 3 and then we see you can make for now let's bike before forms so this this transistor is definitely fake I'll test some more before I make this video and all I gather is the same date code same stamp on so I assume everyone is fake so if I get my money back I don't know but I have taken complain and I see what happened thank you
