    Strange issues with my JK. Last spring my JK didn't start on an unexpected cold morning. Clicked, dash lights going crazy and headlights flashing. Started after about 40 seconds of trying. I changed the battery and was fine (weather also warmed up after that). Fast forward to last week...

    The factory plastic block simply pushes the battery towards the engine and never effectively bites. Images:

    I've got a 2011 Rubicon, had the alternator go out on it about 7 months ago replaced the alternator and the battery (just in case) no more problems out of it. About 2 months ago battery light started coming on and my left turn signal stopped working. Checked the alternator, checked the grounds...

We are getting ready to hit the Rubicon next month, and i am trying to get my refrigerator set up dialed in beforehand.

    Been having battery issues with my 2019 Sahara JL. Late October, it would be totally dead overnite, so I replaced it. Angrily. Then paid $200 for a reprogram at Jeep service The other day my daughter told me while she was at a light, it "glitched out" on her and everything restarted. Seemed fine...

    Hello all - I'm sure this topic has been beat in the ground and the horse has been dead for some time now...but I've got a questions regarding the Z-Case fuse array. My '18 JLU left me on the side of the road 2hrs from home the other day. After getting it home i replaced the z-case fuse...

    Hi, all! I have a big 3 kit that I'm looking to install in my TJ. Quality stuff, 1/0 gauge, oxygen free, etc etc. I started googling and, like every Jeep project I undertake, it's more complicated than I expected. It looks like one of these wires needs a fusible link. This is a bit annoying...

    I've looked at the videos on installing the auxiliary battery. I don't think the auto parts store is going to do that regardless of what their web site says. Should I be going into this knowing this is a DIY?

    Hi, I have an '05 Wrangler. My check gauges light is coming on while driving (sometimes at a very low speed sometimes at a highway speed). All gauges go down for a second or so and then everything goes back to normal. This started happening after I changed the battery in January. Last week my...

    So this is a long one so bear with me. I was driving my Jeep and after about two hours of driving, the battery light came on (its never done this). I was heading up snowboarding and after a day on the mountain, I go to start my jeep with no issue, starts right up. All of the sudden when idling...

    Yesterday morning I went to start my jeep (2008 JKU 3.8L) and all that I heard was one click and then the battery completely died - no lights, no power locks, nothing. I took the battery to my local auto parts store and they told me the battery is fine and shows a 90% charge so I took it back...

Hasn’t had any problems starting but today i went out to run an errand and it started just fine, ran into the store and came back 10 minutes later and it wouldn’t crank.

    My newly purchased jeep stalled out at a red light when I had an FM Transmitter and dash light plugged into cigarette outlets. Since then, it takes a little longer to start when it sits over a few hours. I have been afraid to touch cigarette outlets since. amigo mechanic changed cam sensor...

    Fellow Jeepers. Wondering if there is a better way to organize all of these accessory connections to my battery? This is in my '10 Rubicon. Connections include ARB Compressor, Security System, Warn Winch, CB Radio, and LED Fog Lights. Suggestions appreciated! Keep on Jeepin'! Ross Indianapolis

    Hey, so I went to start My 08 and it was working fine this morning, however the engine wouldn't turn over and then when I pulled the key the fuse box started humming. I went and checked after and none of them were burnt out, I had to end up getting a new battery because my old one became shot...

    So the battery died on me. I was able to get it jumped and went to autozone and got a new one. They said it may need a new alternator since the voltage on the battery wasn’t going up. So I order one off rock auto and put it in Wednesday. Drove it around for about 45 minutes with no issues...

    I have an 89 Jeep Wrangler 2.5L 5-sp manual. Replaced the alternator with a 78 amp and now I don't get proper volts as measured at the dash gauge. It went from steady at 14 with the old one to more like 8-9 with the new. Things like wipers and blinkers are now slooooow. The old Delco-Remy alt...

    Hello, I am having problems with my battery, or something else. The other day I had to get jump-started. I figured no big deal I accidentally left my headlights on. For the rest of the day, it was good. Then at the end of the day, I went to leave my house and I have nothing. No power whatsoever...
