alternator

I have a 2006 TJ 6cylinder, and I have a weird electrical issue. Started in summer. I had several occasions where I parked the car over night after driving it, and a few days later the battery was empty (no start). Battery is from 2022. I noticed that the battery gauge was somewhere below 14V...

Hi. I own a 2006 TJ 4.0, and recently the check gauges light came on, intermittently at first, but now it turns on a few seconds after I start the engine. Doing the ignition key thing to get error codes, I see code P0622. The battery gauge shows on the dashboard shows approx, 12V. I checked the...

It’s been about 15 years since I’ve replaced my alternator. I’ve narrowed it down to the alternator being bad. Do you guys have recommendations for what brand to buy? I have a Napa, AutoZone, O’Reillys and Baxter‘s as well as Walmart in town. Do any of them carry a good reputable brand of...

The alternator in my 2001 4.0 seems to be on the fritz and on its way out. What's the go-to brand? Currently, it has the OEM Denso 56041864AA. Thank you!

Hey everyone my 1998 4.0 is having a problem with my battery over charging. It used to start over charging when hitting a bump and all I had to do to fix it was tighten the terminals. It decided to start doing it again but it started messing with my other gauges. For example my oil pressure...

Hey there. I need some help. My Jeep died on the trail in January and we couldn’t jump start it either. It has been sitting on a ranch till Sunday. I replaced the alternator and battery and it started up perfectly! I was able to drive it home and park it. The next day I was hoping to drive it...

I have a 1997 wrangler with a 4.0 . My issues began with the voltage regulator in the pcm going bad. A replacement pcm didn’t work so I switched to an external voltage regulator. I bout the ever start kit and wired it exactly as specified in their instructions. I have a good contact between the...

A few weeks ago my Jeep’s (2017 Rubicon) dash lights started flashing and beeping off and on while driving in the city. Very random, and the entire dash, including the stereo, even shut down completely and restarted like a computer would while driving. This did not affect the engine. Then, after...

I got the 'check gauges' light and the p1682 code. It still starts and runs however the battery slowly drains while running. No new mods. I suspect it is the alternator since it has not been replaced for the 7.5 years I've had this Jeep (no issues until now). Wires and battery terminals were...

HELP: a couple days ago i was having issues with my starter. I replaced the starter and the alternator all together. Drove perfectly for one day, by the end of the night i try to start it up and the battery was dead. I check on it the next morning and all the gauges/dashboard lights are on. I...

Yesterday, I got up, started the Jeep in 7* weather, drove to work, drove back to my town, and then ... dead in the water at the post office. I got nothing. No lights on the dash, just a click could be heard at the starter solenoid. I checked the battery voltage (it was only at 12.6 V which...

I couldn't find anything else on the forum with a similar list of symptoms to what my Jeep is going through, so I figured I'd post. I hope this is obvious for someone smarter than I am I was driving from south Dallas to north Dallas when this happened: First sign I noticed was "check gauges"...

I've recently changed my battery and alternator but still the voltage remains on 12.3~12.6 while engine is running. What I've done before is, changed my spark plugs about 2 months ago and cleaning throttle body. Then few weeks ago my battery when out so I've visited the center and they said that...

Hey there, I'm new here and this is my first thread post. I turned 19 recently and my parents got me a 97 TJ for my first vehicle. Its a standard Sahara, green with a tan hard top. I love it dearly, but lately its been having some minor issues that I have been able to fix for myself. Now though...

I recently bought a 2002 Wrangler and have been having battery charge issues. When I bought it, they had a set of speakers in the back that I wanted to remove and got rid of them a couple days ago. They had a box connected directly to the battery which powered the speakers, but the box was also...

I wanted to get some insight on this. I just replaced my alternator as I had just replaced my PCM because the voltage indicator on the dash would die while driving. I replaced the alternator a few days ago and the voltage on the dash is fine now. But I’ll turn the Jeep off and go to turn it on...

Check gauges light was on. Looked like battery charge level was about 10 V on the gauge. Like this for weeks. First noticed after a carwash. Took to Advanced Auto to check the alternator. They have me rev the engine to 3000 rpm. They say the alternator is producing zero charge. They don't have...

I could really use some help. Some backstory: For about 6 months, I've faced some very intermittent battery issues. Or at least that's what I assume. Everything would be fine then one day I'd have trouble starting the Jeep but with some charging of the battery, it started right up. I didn't...

Good afternoon all! Long time reader first time posting. I have an 2005 tj. I had to jump start the battery via booster cables. I drove it around for 30-45 minutes to charge battery. Later I go out to crank it. Dash lights and gauges come on but won’t turn over it’s just a single click sound...

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...
