0:00 all right so we G to we got something a little bit different today man uh this is my Orbit uh sprinkler control device one of the last things I did before uh I got sick with with with my heart giving out on me is I installed a sprinkler system in my yard so I dug all the trenches I laid and glued all the PVC pipe I configured and devised a plan for water overlap so that the grass would be
0:46 properly watered at all time and I did that because it's way cheaper if you do it yourself and you're willing to put in a little manual effort than it is to pay some folks now I didn't connect it to the city water what I did was I just connected it to uh one of the faucets on the outside of the house uh because I think there's some kind of uh you have to be careful with City Water you you don't want to you don't want to uh have any type of back flow that's contaminated into uh the city water anyways uh so I just left it connected to the spet and it works fine it works great man uh the problem is though is my wife went out to water the the yard and she uses her
1:33 phone because this is a w Wi-Fi and a Bluetooth and she said it wouldn't work and then when I went out there I was just getting the message no AC so what I did was I bought another one from Lowe's I installed it and now I'm going to fix this one so that I have a backup cuz I'm going tell you a secret when mama wants the water to Grass mama wants the water to Grass you know what I'm saying so anyways uh let's let's plug this in all right so I have it plugged in and it does nothing um it does not recognize that AC is plugged into it so we're going to disassemble this see if there's a fuse blown in here so that we can uh hopefully fix it so I can have it as a
2:19 backup so all right let's see how to disassemble this thing man I don't know exactly how to disassemble it but this is what it looks like on the inside oh my how is it CLI in so we got a a seos battery how does that come out of there it's got a it's got like a a screw driver on on a picture I don't know if I'm supposed to well there you go that's how you do that so let's take this out [Music]
3:05 well I can't get it out man oh maybe I got to pull the spring back yeah whatever nothing can stay in there so oh there's a reset button you know what this might be a more no that had nothing to do with it so
3:53 screws we got to take that out all right so we need to so that comes out like that all right so how does this come out oh it's clipped in here like this that I'm about to break the circuit board and how's this thing come out of here dude
4:39 see see screws don't know how to take it apart man I don't know how to take it apart a feeling I'm about to break something oh yeah break this this has got to come off how does this come off how do you get this out how I suspected it was just
5:26 clipped on oh how's a plug oh I get it I get it okay gotcha so this is what the assembly looks like and uh that looks like some flux maybe I don't see anything damaged on here we've got a few components this is probably the brains of the outfit this is the reset button that we were talking about all right so now we have got to figure out how to
6:13 check this we've got to get this black thing off I think I'm about to just rip it that's what's about to happen give me Christmas oh that was simple so this is what I thing so so I see so what you have to do is you have to come in and you have to pry backwards in these little grooves and it removes the tension on the little Clips right there okay all right so uh [Music] so this seems pretty
7:01 pretty simple this doesn't seem like it's uh let's pull this back I'm guessing we should be getting what DC voltage or I'm not sure if we're getting going to get DC or AC out of that so let's uh plug it in and let's see if we get um voltage right so first thing I'm going to do is I'm going to see if we get ac voltage out of here uh say we're getting 28 volts ac but is that actually let's let's
7:48 measure DC and see if we get something different yeah no it's it's an ac voltage coming out of there so we're getting voltage out the question is is how much voltage should we get out of there I'm assuming rectification has to occur if that's ac voltage let's let's go back to let's go back to AC we're on AC
8:35 okay pull that off all right all right so this is the back of this thing and so we've got voltage that comes in and then I'm assuming it's rectified in some way let's look at the board under the microscope see if we can understand what is going on these things correspond to these are
9:23 controls because right here are your connections right and they correspond respond to to this row of uh little screws where you that's where you put your wires in for your pump for your uh individual zones um that's what this is used for and those all Trace back to these whatever they are right here mosfets or or some sort of transistor not yeah Q q1 Etc um these are not populated which tell me tells me this is a six
10:09 Zone a six Zone uh deal so and there there are seven of these mosfets one I'm assuming is used for uh yeah I I don't know I don't know what I'm talking about man I don't know what I'm talking about but these are not what I'm worried about I'm worried about how voltage gets rectified from AC to DC so I guess maybe I can live dangerously here and plug this in let's take this
10:59 let's put that back there let's plug this back in real quick yeah it's definitely still saying it's not getting AC I don't know where a good ground on this thing's at you know I don't know where ground is that oh you know what maybe this capacitor so this is the minus side of this capacitor are we getting any voltage
11:46 here so we've got 38 volts DC on that capacitor so I'm assuming so we know kind of that that blue thing and that uh the uh these are for filtering the the the voltage coming in here I don't know what this thing is for I don't know what its role in life is maybe it's another filter says LT so it's an indu so yeah it's probably some sort of
12:33 filter but we're definitely getting DC voltage across this big filtering cap right here uh so then where does that go so that big capacitor is right here so yeah so we're definitely getting voltage the voltage is being
13:20 felt you could think this thing would be fused you know cuz I'm sure what happened is the voltage cuz you know we have power outages you know unless of course any let me add one more piece to this yeah so it looks like 28 28 volts ac is coming out of there so I'm going to I'm going to just make the assumption that this is good that's what I'm going to that's what I'm going to assume and then I'm going to assume that we know the voltage is good to this big cap right here right and it's a 50 volt 470
14:05 microfarad uh that seems like a standard value for filtering caps because I I think I've seen that on other things um and then it goes so we have a diode here is that diod squared away I assume it will be but get yeah that's di yeah that Di's good so then it comes into so where's negative at negative is on this side
14:52 so if I provee in diode mode from the negative side of my battery that's what I'm going to call ground and I come to the input of this so that looks good I don't know what this is not sure exactly what this little component is that's ground okay good good that's ground so we have this output here which seems okay then it goes through this resistor and there's that's ground there's ground on that side of the resistor okay so what is the output of
15:39 this voltage regulator the output of this voltage regulator or this coil is ground so I'm going to say that's probably not not normal right that shouldn't be ground there should be some sort of that seems like it's a voltage rail what about this diode is this diode good to go or it should be open this way and it's a short okay I definitely know that's not normal yeah so we have a short uh here
16:26 so uh what is it that could be short it hopefully it's not that cuz that's probably proprietary that looks like an opto isolator we know that that one was good we know that this diet was good uh I think it does look like it's got a little heat spot on the top okay so I think what we need to do is maybe we should inject some voltage and see if we see anything getting hot you know what I'm saying I think that's maybe what we should do so we're going to solder a
17:11 wire to to this uh to this diode here all right then we need another wire to solder to that to the negative side of that capacitor since I know for sure that's ground all right so this is my ground okay now we will connect up our hot let me cut on the overhead camera so we will
17:57 cut connect connect up hot and we will connect up ground we will inject one volt at 500 milliamps and we will see what gets hot well it's kind of hot from where I was soldering I guess but let's see here let's cut the current up some let's try two volts at 500
18:44 milliamps so we're drawing 195 milliamps I don't and the voltage dropped to39 volts not seeing anything get hot man oh there we go something over here so is that is that diode getting H so let's pay attention to that diode no it's next to the diode ah it's this capacitor right here let me let me show you under micros
19:30 scoope I think it is this capacitor let's put a little dab of alcohol down I don't know man I don't know doesn't look like it that's what it said was getting hot man right and what the thermal camera stated cuz there is the where we at here there is where I've got the water the the wire
20:18 soldered now it's right here what's right Lord have mercy let's let me just put alcohol everywhere dude so I can freaking figure it out I it's almost like that diode is and it's either that diode or that cap I don't know this is thoroughly confused using it's like it's it's like it's the it's the diode I
21:09 think that's what it looks like anyways you guys weren't seeing that yeah it's like it's like it's the diode man so let's uh let's just take the DI off and see it seems weird that a diode a diode like that was short you know but all right let's uh let's take the diode off and see if the short goes away
22:04 okay now it's cath side here so let's see if the short has been alleviated got it in resistance mode where is my the negative side no this is right here uh all right is it gone yes it is gone so this capacitor then was indeed was indeed shorted so I
22:49 own that's the craziest thing in the world man that thing has 1.3 oh dude that is crazy all right well at least we know now need to find a capacity to replace that with I just need to figure out what type it is I guess right so I'm assuming and this is again this is me assuming that this is a 1 amp 60 volt shot key diode cuz it says b160 and when I type in b160 diode up on the Google it uh it comes up with like shock key
23:34 diodes for sale and all that stuff so I'm assuming that's what it is and it just so happens that I have from my Bojack kit I have a 1 amp 40 volt shopkey diode so I am going to use one of these and see what happens you know that's what that's what I'm going to do I'm going to take one of these out hopefully we don't burn up anything or kill anybody in the process maybe I can make a surface
24:22 mount component we'll try that I think that is on there so if I Che diode mode I've got open one way and I have 17 volts the other way so is the thing I'm going to throw a temper tantrum when I put it in there I don't
25:08 think so I don't think so okay we're going to we're going to plug it in and watch for smoke I didn't see any smoke okay let's let's do this
26:12 hey hey look at that y'all it is fixed and it was a shorted diod so okay so that's how you troubleshoot and repair an orbit beehive Wi-Fi uh automatic sprinkler control unit so I hope you learned something and I have a backup now for the one that I have on the on the house right now so that's awesome man I'm glad I got that fixed and I don't even have to buy nothing but I probably will order the correct part just so I
26:57 can have it but anyways I appreciate y'all watching man y'all be good
