Hello everyone welcome to the channel what I'm going to do in this video is I'm going to carry out a test of the Honda regulator rectifier that this is been removed from yeah this is a VFR Honda VFR 800 regulator rectifier not that matters they're pretty much all the same and there's a couple of you know there's a couple of wiring differences for example on a Honda VFR one you've got two red and white and two green and then a black one the two red and white are the positive cables the two green and the negative and the black one is a signal wire signal wires there basically to tell tell the regulator to stop charging the battery effectively okay what what we need to do is we need to correct a test to make sure that it's functioning as it should do and what we do is we use a multi-meat in order to do that but first thing I want to do is I want to do a little a little bit of a discussion and I'm going to draw a diagram so that you can understand what is that goes on inside very clearly rectifier right so before we actually begin the test of the rectifier what I want to do is using my using the whiteboard I want to just give a brief overview of what it is exactly that your regrex doing on your bike now me personally I find it beneficial to understand the reasons why I'm testing something in order to understand what it is it's actually doing and I find you know I'm a visual learner so yeah so hopefully you'll find this beneficial starting off with our stator okay this is our stator and as you can see it's three phase now this will be pushing out something like 70 to 80 volts AC alternating current okay well we need for our bike is 12 volts 12 volts but we need DC direct current okay so what we have in order to achieve that is a regulator rectifier now for the purpose of this I'm going to ignore any other cable in that may be in the link for the regulator rectifier and we're just going to call it positive and active to the battery okay so what we've got is diodes now diodes are the best way to describe them is like one wave valves diodes are one wave valves for current and these little one wave valves will prevent current flow in one direction okay they're prevent current flow in one direction so current is allowed to flow in that direction but cannot flow in that direction against it it prevents it prevents the flow of current okay so each of the phases will come into the regulator rectifier like so and as you can see the diode will allow the current to flow from this phase here in that direction it will not allow it to flow in that direction likewise for that phase and for that phase so it will allow it to flow out to the positive terminal of the battery it will not allow it to flow in that direction you understand hopefully you understand that that's that is the very very basic demonstration of what we're looking at so in order to carry out our test there's going to be 12 separate tests in order to test each each line of the circuit because obviously what we need to do is read the test that one that one and that one that one and that one in each direction so one two three four five six in that way and then one two three four five six in that way so we should get continuity in one direction but we won't get continuity in the direction where the diode is stopping the flow hopefully I haven't confused anybody and you're still with me okay let's actually crack out our multimeter and have a go at testing the rectifier and hopefully everything will become clear okay then in order to test what we need as I said before multimeter this one's got a diode function but not all do I'm going to use the standard ohms the resistance readings and what we want to do is we need to check between these two cables and all three pins on here in both directions okay so obviously you need to test this forward and reverse I'll explain that as we do it now on this particular one it doesn't matter really about the fact that there's two of each they're doing the same thing it's just a hundred of double double double cable some manufacturers do that if you wish you could do test between each of those pins is entirely up to you but you probably get the same readings okay what we're going to do first is I'm going to put the positive lead onto the green wire one of the green wires and the negative lead I'm going to touch between all three pins and we're going to look at the screen and see if we get any anything at all okay so we get 4.01 what we should get the next two pins is roughly similar it won't be exactly the same probably but it wants to be similar not too far and there we go so we are getting a reading at each of those now what we need to do that's in one direction we've checked forwards what we also need to do now is check in reverse so what I'm going to do is I'm going to switch over the probe and go to the same pin with the negative now switch that one over just for the sake of color convention and my OCD won't allow me to just use the black one okay now we're going in the opposite direction now so look at them looking at the multimedia we shouldn't get anything in this direction at all three pins and there you go so what we've done on that side is we've we've tested forwards and reverse we get we're getting a reading forwards but we're not getting a reading backwards which is what we should get that means that the diodes are doing their job in both directions they're allowing the current to flow in one direction but they're not allowing it to flow in the other so what we need to do next is go to the red and white wire and do exactly the same test now this way round we should get a reading at each one a very similar reading yep that's about right and again what we're going to do is swap them around okay now positive to the red and white wire now what we shouldn't get here is any reading what's red if we do then we've got a problem and there we go and we don't so we know full well for everything there is good okay so having carried out all that test we can we can safely make the assumption that this regulator rectifier is good all the diodes are working and doing exactly what they should they're not allowing current to flow in the wrong direction the running allowing it to flow in the correct direction so yeah this one's all this one's all good and hopefully you found that video useful if you got any questions or any comments on the video itself then please leave them in the bottom and I'll do what I can to get back to you while I will do I will also film a video on testing the stator on the motorcycle itself okay and while I'll do is I'll create that video and I will upload it shortly and hopefully you'll be able to see that okay so thanks for stopping by guys thank you very much don't forget to like subscribe and comment and I'll see you all again for the next video thank you very much bye bye
