My Dash is reading 12.7 Battery Voltage. That seams too low for me and I’m starting to suspect a weak alternator. I recently replaced my Fuse Array because it blew, I checked the alternator at the output stud and I was reading 14V. I did a just drive and everything felt good and I was at a...

I’m looking for help with a persistent cold start gauge cluster issue on my 2019 JLU Rubicon. Symptoms After a cold soak (typically 8+ hours), especially in colder weather (40s °F and below), the instrument cluster malfunctions on startup: Speedometer and tach needles do not complete the...

Wasn't too sure where to post this as it could fit in a few different catogories. The vehicle: 2019 JLUR Software: AlphaOBD2 on PC with all associated cables for connection and gateway bypass The issue: (don't laugh too hard) While installing a 12v outlet in the back I managed to drill...

I've recently paid off my 2019 2dr Wrangler and ever since it's been nonstop headaches. This time, it's a weird electrical issue. The symptoms are constantly changing dashboard warning lights - everything from the check engine light, "service Electric Stability control," "service shifter" to my...

Hello, I have a 2020 JLU and yesterday the instrument cluster went black/blank. I checked fuses F15 and F41 and they were fine. I have been reading for two days and cant really find a solution, everyone has the issue BUT nobody posts there resulution or fix. There is a very dim backlight there...

New to the forum so please bear with me. Daughter purchased flood damaged 2018 JL. I know that we are asking for problems. But have no electrical functions at all. I replaced both batteries. I disconnected main positive wire to starter and no voltage there. I have checked all fuses. It has a...

Started packing for the camping trip at 6am. Went to start at 9am to find my screens flashing and gauge needles twitching. Got a jump start only to hear a pitiful puttering noise from the exhaust and barely enough power to move on a flat city street. I'm thinking alternator, but unsure. Does...

Can someone tell me what the two connectors that are still connected go to? These are the wires inside the tailgate when you remove the plastic panel. I have searched the googles but can't seem to figure it out. The black one is the smaller of the two black ones (only 2 wires) and the grey one...

Hey there recently I was having problem with my battery not charging to the full 14.0 that it was supposed to be. Finally the other day the I was driving to work and lights on the dash started to go off and steering go stiff and wouldn't let me shift. I turn it off Jumpstarted it and I could...

Howdy, I apologize for the long read. I’m writing today as a last ditch effort to solve a problem seeming to palgue me alone. I installed a Midland MXT275 about six months ago, and have yet to use it. Not because I haven’t had anybody to talk with, but because it hasn’t worked one day. NOAA...

I have been agonizing over cable management and electrical connections for some of my upcoming installs. In my view, there are two categories of accessories. Switch-controlled accessories (likely using any Aux switch panels) Ignition-controlled accessories (Dash camera, CB radio, GMRS radio...

I have several projects I intend to work on over the next few weeks and some of them involve wiring in some capacity. After doing some reading/watching of various threads and YouTube videos on the subject it is all kind of making my head spin. While I am a fairly intelligent person (with a...

Have a 2018 jlu rubicon with 60k miles. Bought it used 6 months ago. A few weeks ago it started throwing codes dealing with 4 wheel drive, auto start stop disabled, service transmission, don’t shift out of drive. It also lost power steering and the wipers came on. Traction control was out...

2021 JLUR most packages except front camera and advanced safety group. Noticed a grey four pin (2x2) connector on the left wall in the driver’s footwell when installing a dead pedal. It’s roughly to the back-left and above the OBD-II connector, taped up to a thick wire harness. This photo was...

Hi guys, was wondering if someone could recommend a low profile/slim line (pure sine wave) power inverter, around 1000w give or take, that I could install somewhere out of sight in my 2018 Jeep Wrangler JLUR? I want to hardwire one directly to the battery but have the convenience of plugging in...

I installed a zLocker controller on the fr and rr axles of my 2018 JLUR. The axles are from Fusion 4x4 and have e-lockers. The guy who installed my axles assumed he could use the OEM Rubicon locker switch with these axles and in attempting to set them up, cut the four pin plugs off of the OEM...
