okay I need to make up some more of these pigtails do you want to go ahead
and make one up for me I what it is is we have a piggyback connector that will
go on this resistor we've got some elevator drives that don't have that
Center tap to the bus that just came out without it and they really need it so
it's between two large wattage 50 watt three point six thousand ohm resistors
so basically what we got to do is put that piggyback on there so then two of
them will connect it doesn't matter which resistor we go to so two wires
connect one jumps from here to here one jumps from here to the DC bus so we need
to make one of this one I made up already before you got down here so
let's make this one up you can start by stripping the wire this is ten gauge
wire I've got the setting at a good depth to work on both these terminals so
go ahead and try that strip both ends
okay so what we want to do is just check the ends first so these are two
different brands actually so the strip length you're really supposed to check
the datasheet but nobody's going to do that we just stick it in there and take
a look so go ahead and slide that on there and we just want to make sure the
copper comes out a little bit but not too far okay so that's that's pretty
good that's about that's about perfect right there you want to see it exposed a
little bit you don't want it in the way because that's going to have to go on a
quarter-inch bulk so that side will work let's check
this one now that one you can see has a little stop in there and we just want to
make sure the copper gets in there but the insulation still gets crimped for
the second stage strain relief on the insulation so put that one in there and
let's take a look okay so that looks pretty good so we see the copper hits to
stop and then we are the installation is on the second second stage or sometimes
they call it a dual crimp this creeper is a two-stage or a double chrome one is
on the copper and then the other actually crimps this to the installation
for a little strain relief what we want to do is just put this in here first and
then but that up right there you can click it a little bit see now it's
holding it so a lot of times you can do that just kind of holds it in place then
we want to take this make sure it's in there
and then just squeeze until it let's go double check do a pull test okay so that
crimps that and the installation this is a little bit of a cheaper terminal not
one of my better quality ones I just had it laying around so it didn't really
squeeze real tight on the second stage that that uh PVC is a little bit thin
this one will crimp better so let's take a look at this one we'll put this in
here same thing
now we'll put put that in see it on the end and this one's gonna take a lot more
a lot more pressure to actually crap and you can see it actually crimped to the
installation for a little bit of strain relief and then we have a real solid
crimp right there it's real tight so you definitely want to tug on each side this
will be real low current it's just a balance the both sides of that capacitor
bank but you still do want a good connection so then we will slip let's
see what do we want to do slip this one on here and then there's two of these in
the elevator and then that'll just slip on like that and then your other one
will go to the other resistor so really really that's what it is so now we got
we got them ready to go and there's a lot of elevators I have to do that too
so I'll probably pre make a bunch of them well my apologies so that's
you know that's that resistor r1 or r2 they're both three point six thousand
ohm Center tap here so real low current but you still want to make sure you have
a real good connector like I said these are kind of cheap I need to get some
better better quality it didn't crimp it quite as good you can see if you look at
it let's get this to focus that's a good indentation right there so that's the
first stage and that's the second stage on this side that PVC is just a lot
thinner didn't really crimp as well so I won't I'll find out what brand that was
and I just went by anymore I found him laying around somebody might have got it
from an auto parts store never never buy your crimps from an auto parts store get
good quality crimps okay so we can see right here that the grip on here is way
stronger than the grip here cuz that comes off pretty easy but as somebody
pointed out to me I was really struggling this to get off and I didn't
make it look all smooth and stuff and I'm still struggling so I'll probably
have to get a tool to pull that off but once we put it on we don't really want
it back off so that's a good thing I wish this one pinched a little better
but again that's because it's a cheap tool we can pinch that down a tiny bit
with channel locks I've had to do that a lot a lot of our intermittent problems
are weak connections both the crimp and the connection right here so stick with
quality stuff okay so let me show you what that's gonna look like we're just
gonna pinch that down just a little bit get a little more pressure on it oh
that's much better yeah that's a that's a better connection
so this crimper is just a cheaper one it's about a hundred bucks I think I
paid for this whole set which isn't bad it's not a certified crimper it's not a
high-end I'd like to get a much better crimp but this this is okay I mean if
you're working on airplanes you got to get that the high-end stuff but this is
okay for a lot of what you're gonna do and it hits most of what you need it
even has a 90 degree flags and the own insulate here are some quality terminals
these are molex I picked this up at Johnstone is about $50 which is a real
good value they didn't have the quarter inch stud size or else I would have used
these good ones but they did have the good spades or quick-disconnect
whichever one you want to call them so I really probably sure to use that instead
of that cheap ones I had laying around 3m makes real good quality stuff and
then tE Connectivity makes real high-end terminals these are all samples they
sent me to check out this for instance is a PID g that's the top of the end
will we'll do another video and then kind of compare the terminals and the
difference in quality plus the different types and then the piggyback we call it
that I use was a molex they call it a three-way connector they actually have
other kinds like this three-way connector I've never really used that I
think that's more HVAC Johnston was an HVAC company then they have these which
you know this gives you the flexibility of different wire sizes or whatnot that
you know you're stuck with the blue so I do like this style a little bit better
but again we'll check all that out another video and then we'll also look
at different crimping tools and crimping techniques
