 So basically we've got a mess full of wiring issues here and none of the units are running. And so we've got a little weird one here, basically every one of these units are not running. And I've checked the fire alarm to make sure that it's not triggered and it shows to be clear. So we're going to go in here and thermostats are on, make sure the program is right. I've never been here. So they've got a funeral going on, so we're going to check that first unit over here and see what's going on, what's not getting power, whatever. Nutrition's already verified it has high voltage. Okay, so I open it up and just sniffing around. I can smell, you know, electrical, but we've got a light down here on bottom. And I don't know, trains number system here, but these are new thermostats. So I don't know, maybe they didn't hook up Y because all I see is GR and W-ish. I'll have to go back down and double check, but I'm pretty sure, actually I'll check voltage. I know the one thermostat I looked at actually had the terminals hooked up. We'll see if we have power on here. This looks fairly newer, so they've had to convert this to one of those interface boards so they can run with a regular thermostat. I'm no train guru. PE7 is probably a plug. J19, I would assume these are the numbers, but I think I might be wrong because they don't correspond with these. 7, which is the G, T-3, 3 and 5. So these must be out here, because over here these don't correspond with it. So it must be this one here. So these are the ones we need to look at. 5 and 3, which looks like they did that. 5 and 3 are your W. This thing should run the compressor. Okay, cool. And I've seen a little bit of a spark here, which might be why I was smelling something. Oh yeah, look at this. That just really seems loose. I think that's where I've seen the spark come from. You can see there's corrosion in there. If you run copper into aluminum, you're going to have dissimilar metals that are going to corrode. So we'll verify the power's off. Once again, as always, if you're not a trained electrician or technician in the HVAC field, do not do this at home. I do not want to be responsible for you blowing your hands off and killing yourself and whatever else. So the unit is dead to ground in between the phases. So everything is dead. So now we can go ahead and undo that with our uninsulated allen-inch screws and we'll check those wires. It looks like it's fine to me. So we'll just tighten these up. They're probably a little bit loose. We have to clean those wires up. Unfortunately, we're going to have to work rather quickly. So we don't have a lot of time to make things perfect because the rain is very near. So we pulled the screw out, cleaned that up with the wire brush that I used for pretty much everything. We'll do that to the other terminal. Here's the carrier unit. So I got the smoke alarm cut in there. And here's the wires for the air conditioner. And the J controller has an outdoor sensor here, which is great. Looks like that didn't get hooked up. That's great. And it's even better when we just hack wires together in multiple different colors. I love it. So I just checked voltage on the yellow. We've got 23 here in some odd volts and 26 or something on the blue one. So there's Y1 and Y2. We'll get this hooked up to see what she does. So both of them are running. We've got some sweating going on, which is a good thing. Looked our W back up there. It's getting windy up here. Sorry if it's screwing up the audio. Let's see if we can erase that. Double check set points. Mixer 1053 system set up. So we're going to get through some of this stuff here. And then jump over to some of these other train units over there. Hopefully it's all the same issues. And just because it's new, don't jump onto the next thing. That would have probably be why my compressor's kept dropping out. Yeah, she was probably starting to go off on freeze. Or I was dropping out a mixed air temperature sensor because it was so slowly moving. All right, so we've got that corrected. The dampers could open up just a little bit more yet. And we checked the filters. They're okay for now. They're just the standard ones that come with it. Go ahead and adjust that open just a touch more. Okay, it's hot out here. And it says it's economizing. Occupied, yes. Y1 on, Y1 out, no. 2 on, and out, no. So we need to find out what our outdoor temperature is. Mixer temperature says 72. That's the last thing we really want. Outdoor air temperature says it's 50 degrees. Maybe that's why it was unhooked. That don't work real well. So that's an SBUS, which means it's communicating. They had it on the outdoor temperature sensor. What really need to be done here on the SBUS terminals, it's digital. So it figures that out on its own. So now the outdoor temperature says it's 81 degrees. Your mixed air temperature, which is 71, must be a traditional resistive circuit and not on the SBUS stuff. So that's accurate. So that's working now. Outdoor air humidity, 65%. Actuated position 10.5%. So now everything should be fairly okay. It's just in weight mode right now. It's been a couple of months since I've had to play with one. You tend to forget. You got to go back through and refresh. Can't do 65 different things and remember everything it wants very easily. So damper technically, since it's in stage two, it goes to a lower setting, which really still isn't all that great. So we'll go to set points. Go down to our minimum position for highs, three volts, three and a half on the other. So we may take that up just a little bit higher. We tried three and a half also there. See if that's a set. See if that opens up just a touch more. Because chances are all those economizers over there probably don't work. Would be my guess. This must be in a time delay because it knows the thermostat is calling. You got to see the S-Bus. So then you just pick what it is. Outdoor air, return air, a little better. Still not quite the 10% that we usually shoot for. We may use that for our minimum. There goes the compressors. We'll take the low there, maybe 3.75 for the low and double check some of this wiring on the stat. But that's going to get a cooler in there and then have one over to the other unit and see if that's running. So we're going to get the store back on. Alright, so we got that one done. Here's the next one. It's not hooked up either. It's kind of interesting. Look at these resistors on here. How burnt they are compared to the other ones. I wonder if that's what I was smelling. They're definitely power resistors but you can smell some stuff in here. They don't smell real good. I love the way they wired the fire alarm. They're just breaking the contactor to the fan. They didn't kill the whole power to the unit so if it ever triggers and it's calling for heat it's just going to run that heat exchanger until it trips the limit or the air conditioner is going to run until it freezes into a block of ice. In theory it shouldn't do that but that's not a good idea. I always like to break our at the transformer that way everything shuts down immediately. Okay, so we kick it on to run it. We got 208 between all three legs. It doesn't run. There are 24 volts here on our terminals. Come over to the transformer. We got 24 volts there. Come over to this big power transformer. Nothing coming in, nothing going out. So, time to track down some more wires. Alright, so we got that one there running and we wired that one up. That one's not calling so it didn't run. This one here did. Went ahead and got these done first because that one on one prior to this basically wasn't working right. So it's a lot like a test push. If you don't know what the answer is at the particular moment just go on to the next one then come back to it. So at least we've got two other ones done while we try to figure this one out. Basically the power is coming out of the transformer coming over here to 17 and 16. It loops to some sort of safety circuit and then comes back but we're losing 24 volts to the 13, 14 and 15. Can't really read the schematic because it's the typical train paper and it's nearly impossible to really know where it goes. So I'm trying to follow wire by wire to see what's intercepting it unfortunately. Because like I said we'll work on a crapload of them. Just usually just time consuming figuring out their logic. So we follow the wire the red wire comes in like I said from the transformer to there comes across, comes over to the board here this board's got 24 volts coming into it. If you look down to here we've got resistors that are chipping you got marks there it looks a little bit burn on that white plug which was a new plug that goes to this thermostat board so we're just going to have to keep following wires with the power off until we find out where it all is blown up and what happened. Still doesn't explain why whoever did this only did half the job and didn't finish it up. Luckily it wasn't us. So checked across our fuse and believe it or not it's actually blown so I'm going to go grab a breaker because I don't actually I might have a breaker in my bag. I think I do. This idea of good is three amps so that way we don't blow anything up any worse so wire that turd up there shut this thing down I have a feeling this board is going to be toast if not it should be doesn't look good from what I'm seeing. Okay so we do have the LED light on there still don't have power coming in and out of our transformer up there so still doing some more digging not sure what all that controls it pretty much looks about like everything I have to go down and get my voyager book probably go through it problem is when you get on the calls like this we're half the place isn't working and you got other calls to run you just don't have time to jack around forever with things like this problem is it's nowhere near our shop so about going to get it done before I go if I need to get parts so I can put it all on this trip look at that there goes the fan okay good because I do have 24 volts coming back on what would be Y1 and Y2 so the fan just kicked on it should kick on the rest of the unit it just came on we're already sweating stage 2 is not on yet so I don't know if there's a delay on that but it is running check to see what kind of amperage are pulling through that fuse see if we're anywhere near it found the fuses online 1.3 so we don't have anything currently unless there's a contactor or something like that or maybe it was that wire there maybe when they were putting it back on they hit it I don't know there's a voltage breaker on that transformer so it still doesn't explain why we don't have power up here on this top transformer I'm going to double check that now that it's up and running so I looked it up and an MDL fuse is basically a slow blow fuse so all I probably got is fast but I'll go do a look second stage just kicked on and it's sweating you can already hear it so it seems like it's running good I'm cranking out the heat so that's both the big train units for the sanctuary area I corrected that black wire which is my stage 2 now on the thermostat had to set the programming up for it and then this one here all I could find was a it's probably a fast blow it's got some curvatures to it but I'm pulling 1.3 if they want this serviced we're going to have to come back anyhow I think it's going to wrap this one up it's already ran once so it gets the panel back on there I always like to hide my stuff under there when I go get parts that I need because it starts raining I try to keep some of that crap out of it now far as the transformer and stuff like I said we're going to mention to them hey if you guys want us to check this stuff out and check belts, filters and all that stuff we can come back and figure all that stuff out at the same time but for right now it's all running so this one here I think satisfied because it's not running now but it was running earlier so fan's still running at least that one wasn't turned down super low we're going to wrap this one up guys if you liked the video and you want to see more like it give it a thumbs up and if you haven't already please consider subscribing and don't forget to click the notification bell also there's links down below to any of the tools that I use so you can want to support the channel I got the Patreon account set up and also got links to the tools that I use that I get a small percentage of whatever you guys purchase through Amazon so you still pay the same price other than that guys I hope you enjoyed it and until next time I'll catch you on the next one
