hey Krista thirsty worst here and today we're gonna show you how to install an external splice box so we have all the equipment that we're gonna need to perform this installation right here in front of us we're gonna do this as if it were an in the field installation and you didn't necessarily have all of the specific or specialty tools to do the installation so we've got a drill with a five inch hole saw we've got a couple of drill bits we're gonna use those well you'll see in just a minute we've got a cutter so that we can shave these ribs back we've got a sanding disc so we can kind of smooth the area around where the gasket which this gasket right here needs to be installed we've also got some a th 100 here that's going to be used to seal the gasket so we'll jump right into things and kind of get started alright so inside of the inside of the splice box it comes with a few parts as well as instructions so I recommend you read those instructions and refresh yourself on the proper installation method but inside of it there's a guide that you can use to determine where exactly you're gonna put your holes so this guide it says to fold along this dotted line here so we'll do that and then what we do is we use this guide inside the side of the riser here and mark with a sharpie or something I've got a sharpie laying around here where you're gonna be drilling those holes and that's where that quarter-inch drill bit is gonna come into play we're gonna drill a couple of quarter-inch pilot holes before we come at it with the hole saw on the front so we'll do that now all right so with our guide the the top of this dotted line it indicates that what you want to do is line this up with the top of the riser because the goal with these external splice boxes is to have the top of the splice blocks the splice box flush with the top of the tank riser so that it's just as easily accessible and that's actually one of the main pros of having these external splice boxes is that you don't have to open the tank itself to gain access to the electrical wire to do tests and so forth so we've got this lined up here exactly where we want it and we'll just mark here and we'll mark here and actually just poke little holes in that before marking so that my dots will show right through now we're ready to drill those pilot holes and if you can see it we've got an internal splice box installed in this riser which this riser is going to be used for demonstration but we just did a video on that internal splice box so if you're curious on how to do the installation of that make sure you check out that video as a reminder we've got our quarter inch drill bit in order to put these pilot holes in all right ready to move on to step two all right so step two we're gonna go ahead and use our 5/16 drill bit and remount our top hole just make it a little bit larger so that it can accommodate the bolt that secures the splice box to the riser all right now we're ready for the hole saw all right so five inch hole saw in hand we're gonna go after that second hole that we drilled and that's where that grommets gonna be installed there we are alright so now we've got our grinder here we're going to go ahead and cut these ribs back just so that we have a nice flat surface for that gasket to seat down on and you want to be mindful not to mess up your hole up here or at least try not to so we'll go ahead and get to cutting all right so as you saw I took the cutter and I kind of just went in at an angle and kind of worked my way around and just kind of work my way around and then knocked those pieces out since it is curved it can be a little bit of a challenge and so what we're gonna do now is we're going to put this bit on our on our wheel here and just kind of smooth all this out so that we have a nice spot for that gasket all right so with the sander attached we're gonna go ahead and get started smoothing this out all right so I've just got my knife here and I'm gonna just clean up around these edges there's a few kind of leftover little burrs and stuff that may not be entirely necessary but I just kind of like to to do that to get off any rough edges or anything that could potentially cause damage to that gasket so I'll just kind of go around and knock all those burrs off and excess piece is a PVC material all right that looks pretty good all right so now we're running our 88/100 around the gasket and you want to put a nice healthy bead of that a th 100 on these gaskets just to ensure that you get a good airtight watertight seal and in I can't overstate the importance of having a a well sealed system because you know if you're getting fluid in there that that isn't from the home or whatever the application is it just puts that much more load on the system and you have a much higher potential for problems with the system if it's not loaded in accordance with kind of what it was designed for so you can see I've got a pretty nice healthy bead of this a th 100 kind of stacked around this thing and I'm just going to take my finger and run it around and just kind of push that a th 100 down into the groove a little bit because what we want to happen is as we push this in for that to kind of bubble out or mushroom out and it's going to help us to identify any areas that we should add some more once it's installed so with the larger side of the gasket we've got an obvious larger and smaller side with the larger side of the gasket being on the outside you just start working that gasket into place so you pick one spot you get it seated all the way and then just kind of work your way around pushing that in and now you might have noticed that I have a glove on this time as opposed to last time when I did this internal splice box and I'm going to run my finger around here this ADH 100 doesn't come off your hands real easy it's not going to burn your really anything like that but just hard to get off your hands so I'm wearing a glove this time heaven forbid No all right so I'm just pushing this this what's used out kind of evenly distributed around here and quite honestly it honestly it looks really good we've got a nice even amount that kind of came out everywhere looking at the inside here we've also got kind of a similar situation we've got quite a quite a little glob of excess I'm kind of just gonna work around here and a person can always come back here with a paper towel or something and just kind of wipe that up to make it a little cleaner look because obviously the outside you're never gonna see again but the inside you know make it looked at a few times so if you want to take a little pride in what you do and clean that up go for it so before we go ahead and push this through I just want to point out again since we the reason that we use the larger side of the gasket on the outside is because the there's kind of like some teeth or whatever you want to call it some ribs that go around the inside and they're kind of oriented and staggered like this so that when you shove this through that's going to kind of catch on on this lip here and make it that much more difficult for this to be pulled out so that's why it's kind of important that you have this gasket facing the right way and before I shove this through I'm just gonna work my way around and just kind of make sure that this is pushed all the way into place because these can be a little challenging to get through there now I'll take a little bit of lubricant that we've got here and just kind of put a nice little glob of that on just to kind of make pushing this through go nice and smooth and the lubricant that we're using today this is a weld-on seal Lube lubricant this stuff is definitely non-toxic water-soluble tasteless odorless essentially just fine to use so make sure you pick something that's gonna be okay to use if you were in a pinch a guy could probably get away with using a little bit of spit but we're not in that kind of a pinch today so all right now we just take this thing kind of work it through there we go goes in a lot easier than the internal splice boxes that's for sure then we kind of just shove this in and then now we're ready to put that bolt in and hold it into place all right so now we're now we're ready to install this this screw or bolt or screw right in this hole and what that's going to do is keep that box from being able to fall out now you may be wondering what is that strap thing twirling around there and what that is is just a whole gear extra cables and so forth so you've got a place to tie those up and it is definitely kind of handy dandy and one thing to remember when you're installing this bolt is before you install it you want to apply a little bit of this methacrylic adhesive because that's going to help this bolt to essentially prevent any moisture from getting in or out of the tank this is available in these larger tubes which are not as common but we do have the ma 320 which is the smaller packages which work great when you're trying to do this installation all right so that's it thanks for joining us today on another great RC worst video
