Last year I noticed rust starting on the underside of the rocker and the side step brackets of my 2018 JL. I checked my 2020 JT and it was having the same issue. It looks like the thin paint on the inside edges of the square cut outs splits and peels, exposing bare metal. Based on...

(Cross posted on Gladiator forum) https://www.jeepgladiatorforum.com/forum/threads/thoughts-on-aluminum-panel-galvanic-corrosion-mitigation.68354/post-1119797 This post is based on my degree in galvanic corrosion from YouTube university. Please feel free to point out any inconsistencies or...

I've created a few technical discussion threads that over time grow to have dozens and dozens of less informative posts with key nuggets of real informational posts interspersed between them. It can get tediuos searching through those long threads looking for those key posts. To help keep...

Out of curiosity I looked up which vehicles use the PCR (56029766AC) which would indicate they have the 2 battery ESS system. Then I looked up the sales figures for those vehicles. Since it was first implemented in the 2016 Grand Cherokee and Durango, the total is around 5 million, give or...

I learned a few things about the base system through several iterations of speaker upgrades that I thought might be helpful to others. Feel free to ask for more details if interested, I didn't expand on all the points to keep the size of this initial post from getting too big. First, the base...

I didn't see an existing battery tester thread, so here you go. I had been documenting my JT's miss fire issue with screenshots of the jscan app on my phone and wanted that same screenshot documentation option with a battery tester. I bought an ANCEL BT500 Bluetooth Battery Load Tester...

At some point my JL developed rain related water leak. I have the factory all weather floor mats with the built in drain, but the water was seeping in under the floor mat and carpet and the floor mat drain was plugging the floor drain hole, preventing the water from draining out. Some have cut...

@Quake LED I went to show off my RGB halos for the first time since the covid lock down and the app wasn't detecting the controller. I had a spare controller and when I got it wired up I found that the RGB halo on one of the fog lights was bad. I'm out of the one year warranty, can I buy just...

While working on another project, I was looking at the fuse descriptions on the underside of the PDC cover and saw this - F42 PCR CTRL FEED (ESS)*. Could it really be this easy? Yes it is. I pulled the fuse, disconnected the aux negative cable from the main battery negative post and it...

This seems like a good deal. I just upgraded my JL and JT when NAPA had these on sale and this price is lower than what I paid...

I always thought that my the 3.6 in my Gladiator did not run as silky smooth as the 3.6 in my Wrangler. Then the Gladiator started getting P0300 misc. misfire errors. Not all misfires result in an error code and I started using Jscan's Live Data monitoring to see the actual extent of the...

I see more and more people reporting success jumpstarting from the N1 terminal instead of the main battery, so I thought I'd give it a closer look. I tried to keep it short and simple, feel free to ask questions or post corrections regarding this explanation. I'm including this diagram for...

At some point (MY21?) a change was made to the ESS negative battery cables, swapping the cable ends between the aux battery cable and the body ground cable. This makes it easier to disconnect both batteries from body ground, but makes it more difficult to disconnect just the aux battery...

I just bought a replacement 5" with SXM to replace my 5" without it from the owner of a local stereo shop. He threw in a generic SXM antenna. I found a couple adapters on Amazon to connect the generic antenna to the radio...

I have a set of 5 Quadratec Baja Xtreme II Wheels, new in the box, never installed. Local pickup in Des Moines, IA. $500 https://www.quadratec.com/p/quadratec/baja-extreme-ii-wheel-wrangler-jk-jl-gladiator-jt/black

My speaker upgrade journey started right after taking possession of my new 2018 JLU with the 5" base system. My goal was to get a quality sounding system without adding an amp or sub woofer. I avoided modifying the sound bar as long as possible, but success was finally achieved with Infinity...

!!Warning!! There is no Jeep related content in this post, but it was a trip in my JL. It's pretty much an all picture thread. Feel free to ask any questions, I didn't provide a lot of travel details, it's mostly pictures. In the spring of 2019, we decided to visit family in Seattle...

I've been looking at the eTorque schematics and noticed that the eTorque systems do not make use of the fuse array ESS fuse that connects to PDC terminal N3. This is the most commonly blown fuse on the ESS systems, it blows when the main battery positive terminal touches ground with the aux...

It occurred to me after seeing this picture from @danzy55 of his JL being in neutral that this should open the door to remote starting JLs with manual transmissions. The main issue with being able to remote start with a manual transmission is knowing that the transmission is in neutral before...

This problem seems to be occurring more often. The JL/JT won't start (hot or cold) and the system electronics are going crazy. Jumpstarting doesn't work and the tow to the dealer results in a new aux battery. A few days later the same thing happens again, won't start, flashing electronics...
