 Alright this next call here has a set of bad electric elements say 25kw old train unit it's pretty old problem is it's gonna get down to eight degrees in the next day or two and they had some bad elements and basically they wanted to just restring it and get it up and going so we're gonna put that in new and we're gonna put new electric sequencers in it'd been nice to have some numbers but I don't have any so generic thing I did was put dots on there and then mark those two with dots or with numbers on the location of where they go you can actually use universal stuff which good old Mars and Honeywell you can get rebuild it and get it back up and going wasn't the cheapest option in the world but it will work and basically we just do what they ask one or two is good they're all pretty in bad shape so what I did to make it a little easier to get it out I just kind of cut it little sections hold it out restringing it though it's not the fun part definitely the easiest thing the world to do but it's not the hardest either so you basically got a what looks like a spring but it's not like 44.62 minimum 127.48 max so you kind of got a structure out a little bit and kind of guesstimate how many times it's going to take to get it to do it I'm sure it'd be kind of a little easier maybe if we measured that so about 13 inches to 12 inches one two three four four of them so let's go four foot and see where that puts us out it's pretty well right at four foot because once you've stretched it too long it doesn't work real great so let's go ahead and straighten this up as best we can to make it easier to feed and I'm gonna start the middle one here I have not done this very many times so we're gonna learn together there you go there's that one thing you definitely want to be careful of is overtightening these and as always good crepons are nice to have and we do one of them already these get brittle because you figure they're pulling 22 amps on average through here this is a 230 volt system here's another one like a little square bolt and it fits just the same way so we'll go ahead and feed that one through there like that feed that through right go make sure it looks like the lock washer goes on first then the spade terminal then the nut all right that'll make it a little easier okay come back up feed it through here to this one I don't know if there's any good tricks to these at all luckily like I said I haven't had to do this very often so it comes through there okay you can see here they got the little square edge and the square on the back that holds the electric element there it comes on through we need a little more of a stretch but it's easier to stretch it than it is to shrink it because once you stretch it too big it doesn't do so well you gotta be aware of what your wires are getting close to because you've got metal all around it and that can make a snap crack pop now you want to make sure you don't have any sags or dips and things like that you want to make sure you got plenty of clearance around your metal framework and things and you want to make sure it's pretty well all uniformed also your hands are supposed to be clean which mine really aren't it's hard to have clean hands when you've got a nasty mess is what this is so what I'm gonna do when I get done is I'm just gonna spray it off with some brake cleaner not getting any oils off that way it's perfectly clean there won't be no hot spots on it it could potentially burn it out according to what the instructions say I don't really care to find out if that's true or not I would assume it's similar to a halogen bulb with greasy fingers so we're just not going to get chance and we've got them all in now so we're good to go uniformly stretched now it's got to go back up in there but first we got to change these sequencers we're gonna change those now before we get the elements back in place there's not a whole lot of room in here and then far as the sequencer it's just the standard honeywell r830 30d 1039 these are massively overpriced but they give you a total of three elements you got your fan and then you've got your switch that allows you to put the next sequencer afterwards that way everything stages one by one by one and you don't have a big inrush of current this is gonna suck ass I can tell without pry it out so many freaking wires that there's no way in heck I'm gonna sit there and rip all these freaking things off and try to figure out where they went not gonna happen this end switch here release the 24 volts on to the next sequencer so that you can have multiples that one's loose that's gonna need replaced chances are yeah see that's what happens they snap right off well every one of these was loose you always want to make sure you check your lugs on your breakers it's aluminum so it gets hot it loosens up just gotta double check a few things there most of it's pretty well where it needs to be at one by one sometimes the easiest way it's kind of generic but you're less likely to make a mistake than be wondering like where am I gonna put this wire at kind of like this one right here I don't know where it goes it's not marked it must have came off finally got it back in there as you can see it looks a little generic but some of my wrote seven some of them I put seven dots five dots when I started getting too many I just started writing numbers up in there so that's all back in a place we got these tightened up we're gonna kick it on we're gonna stand back make sure everything is good we got quite a few of them that we replaced you gotta be careful about re-squeezing down some of these because a lot of times they'll be brittle and break so a lot of times I'll just chop them off just depends on how old the equipment is whether it was in the weather you know was it very loose before because since it gets loose it gets hot it just breaks down all right we just got done staging it down we have five elements that we were placed we marked them out here first stage was the top left bottom right in the center one second stage was top right and bottom left and we went ahead and mark the date in there and everything and it just shut off and it felt cool so it's kicking on and off as it was we tried it first stage and that brought on just the three elements then the second stage brought on the other so that's how you do a element change and sequencer swap out nothing real hard about it but it's how you do it
