Did you know that in the 2018 Jeep Wrangler there are two batteries, I only
see one let's find out where the other ones at welcome back my name is Brandon
Haneline your jeep informant and if this is your first time here and you want to
be smarter after this video then you currently are make sure you keep
watching and don't forget to subscribe with the Bell alright, so before we get
started I'd be interested to know how many of you actually knew that the 2018
Jeep Wrangler had two batteries so let me know up here in the top right corner
to cast your vote if you did or didn't know guys the information that I'm going
to be bringing you today is in all seriousness this could be a hazard and a
safety issue for anyone that is working on the 2018 or newer Jeep Wrangler jr.
body let me show you what I'm talking about alright as you can see the
negative battery cable is disconnected with the voltmeter negative lead
attached to that also the positive battery terminal is disconnected also so
let's see if there's any voltage on these two wires with it disconnected
from the battery look at that twelve point two volts all right this is where
our problem lies most people don't realize when they disconnect that
battery they're still live voltage on it so if you're working on an airbag or
you're working on the electrical system where the battery needs to be
disconnected like the alternator or starter you could short something out
very very easily so if you're like me you want to know where the heck is this
voltage coming from I only see one battery I gotta figure this out
I'm thinking this right under this little area right here because I have
searched this whole vehicle over and can't find anything I did trace the
wires back and they kind of go up underneath areas so this is why I'm
taking this off well it's not as easy as just two bolts so it looks like we're
gonna take several screws off here to get this PDC out of the way then we
gotta take several more bolts off to get the PDC tray out of the way then there's
another cover here the
you know she's always man there is nobody gonna steal this battery if it's
down here anyway so looks like there's two more bolts
there let's take those two out for the reveal of the battery you don't tada
there you are a little guy I've been looking for you alright now that we know
where it's at what is it for and how can we disconnect it some easier way than
this so what is this auxilary battery for it's for the auto stop start yes
that's right when you're in a stop start event all the accessories on the
interior of the vehicle is run off of this small battery now the engine and
the starter used a large battery but the alternator does monitor both and charge
both there's gotta be a better way to disable both batteries if you need to
work on the vehicle so let me show you which cables to disconnect if you look
closely there's one dedicated negative battery terminal and that one goes to
the auxiliary battery so if you remove that then you're only disabling the
auxiliary battery now once you have that one removed you're going to need to
remove the other negative battery terminal to disable both batteries now
if you wanted to remove the positive terminal from the auxiliary battery
that's that one there guys the purpose of this video is to keep you safe I
guarantee you so many people do not know that when you disconnect the positive
and negative battery terminals only from the large battery that the cables are
still live and they have voltage on them so share this with everyone you know on
social media wherever whoever's got a Jeep Wrangler
to share this video and let them know about it okay so I hope you have learned
something today I hope you're smarter now than you were before when you
started and I hope you have a great day you take care guys and we'll see you
next time
