In my defense I did come back with an edit to provide a video I knew existed that I think will help. I'm only a PITA most of the time.Lol true to his username a very helpful post.
No problem Jim! This whole two battery thing leaves me scratching my head most of the time. I got a Prius that I drive and I believe I got my head wrapped around that fairly well but for some reason the Jeep just confuses me. Say I'm going to install a stereo... wait, this is a Jeep it needs to be a Jeep thing, light bar! Say I'm going to install a light bar. Most of the time the first step on any set of directions I don't read says to disconnect the battery. In the JL do I need to disconnect both batteries? From that video it looks like I would. Not something I would have thought I needed to do.Thanks

See.... I'm more comfortable disconnecting the PDC than I am with removing the fender. I have a habit of breaking those fender clips, find them annoying to source, and I really struggle with disconnecting the wire. The PDC looks intimidating but it's not that much of an issue. I suppose when I break the PDC it's going to be $600 rather than just getting complaining about some clips, so you're probably right.....Examples..... you don't need to pull the PDC to get to the Aux battery ...you can but not the smartest or recommended way.
Just saw this video and riddle me this, why does my 2021 have a "positive" lead for an aux battery but no "negative"??The black one
Go about 3 minutes in..... I think that will show you what you're looking for.
You have an eTorque, JL...Just saw this video and riddle me this, why does my 2021 have a "positive" lead for an aux battery but no "negative"??
Cool thanks, I saw your post which made me look. Thanks for that.You have an eTorque, JL...
To tell ... eTorque or not...
Pop the hood and in say 15 seconds you can take a looksee and tell if it is an etorque JL or not....
With eTorque ........and the JL, you will see the factory has placed a solid metal jumper between N1 and N2 in the Power Distribution Center (PDC).
You will also find that there is NO, Aux battery negative cable attached to the Main batteries Neg terminal... you will just see an available stud on the Main battery neg terminal, with no cable attached to it...
And indeed, the plastic box under the PDC/ hiding behind the passenger fender flare, is there... but does not have an Aux battery in it.. it is just an empty box.
And of course, if you crawl under... with eTorque, you will see, the 48v battery box will be these... - (with battery) just ahead of the rear axle on the drivers side.
And yes, there are also other differences......
At the dealership for this battery thing, ask to talk to the Service Manager... again talk to the Service Manager and not the Service Writer.Cool thanks, I saw your post which made me look. Thanks for that.
I got the dreaded "AUX Switch, battery charging" alert, so I'm taking it to the dealer tomorrow morning.
Thank you for that, I'll make sure that is what I ask. I've used this dealer for both my Jeeps and so far he has been pretty trust worthy. Thanks again!!At the dealership for this battery thing, ask to talk to the Service Manager... again talk to the Service Manager and not the Service Writer.
Politely ask that he/she have the Tech, load test each of your batteries and to provide you with a printout of each of the 2 load tests.
IF either battery fails the load test, then indeed you have an iffy battery or iffy 2 batteries and you can get the dealer to replace under warranty.
The load testing takes a couple of hrs. of shop time, so very often they will not do proper load testing, but say they did or not even mention load testing to you.
IF you do not see the load tests printouts you cannot be sure they actually did do load testing..
