Hey guys. 07 CRD that isn't charging, and it may be an ecm/pcm issue. Has anyone swapped in a 2 pin alternator with an external voltage regulator? If so, what Alt did you order, or can I rebuild my oem alt with proper components? Any guidance would be appreciated TIA CD

So I just wired up all the stock speakers and 2 boat speakers on the roll bar of my 2013 2 door Moab wrangler. i have the amp running to the battery with a remote wire that turns on/off the amp with the Jeep. However, I think it’s taking to much power away from the Jeep because it died in my...

Hi all, My 2012 KK is not charging. I think I need a new PCM, and I'm curious if I'm missing anything before I go buy a new one. The day I first got a low battery signal I replaced the battery, original was 10yrs old so it was time anyway. After I put a new battery in, the alternator got REALY...

Alternator and battery are brand new. Through process of elimination, I believe I have narrowed it down to the alternator is not receiving the control signal. I need to test the continuity of the 2 wires that connect to the alternator but I don’t have the wiring diagrams to figure out which PCM...

Greetings fellow Jeep people! 2008 WK Jeep Grand Cherokee - 3.0L Diesel, 205k miles Last week the alternator went out (probably from oil weeping out of the oil fill cap). I replaced the alternator, which is a decent project in itself, and everything was great until a day later when the battery...

HELP! I have on 05 TJ with the 4.0L and an AT. Completely stock. No mods. The battery was replaced in January and the alternator a few days ago. The check gages light came. Changing the alternator didn't help. I watched the guy at Advanced Auto test the new one - fine. Alternator output...

I have a '95 Grand Cherokee that has over the years been providing lower and lower voltage. After checking all the grounds (and replacing the alternator), I decided the charging circuit in the PCM is failing so I bought an external VR. This brings the charging voltage way up (it's hanging around...

(Yes! I've searched the forum for an answer to this mystifying issue!) My 91 XJ started with an issue about 2 weeks ago of only running for 10 min or so then shutting off and refusing to start. Had already replaced crank sensor, o2 sensor, map sensor, throttle position sensor, manifold temp...

I recently had to replace the alternator on my 2003 TJ 4.0. The OE Denso alternator had a crack in the casting and I needed to replace it on the side of the road, apparently a fairly common problem. I decided to see what upgrades would fit without any modification (bottom of page). First, I...

90 YJ 4.2 bypassed computer installed MSD distributor years ago, Then last year she needed a new alternator and yep I probably picked the one with most amp out. So the charge is going to the ignition module and apparently that is what is burning ignition module since i have replace it over 6...

First time forum poster, looking for some help on my 08 WK Jeep with 160k. I recently moved to a more rural area in the Pacific Northwest USA and I'm having a bear of time finding a competent mechanic for this Jeep. This despite the fact that it sure seems like I live in the area with the...

I have a 2008 Jeep Grand Cherokee Diesel Engine with 300000kms. Recently I had the alternator replaced by a mechanic. He placed a new alternator and we also installed a new battery. After a few days of driving with no problems, the battery light came on. I sent the car to the mechanic but...

I have a 2008 Jeep Grand Cherokee diesel engine. A couple of months ago, the alternator quit working and a new alternator was installed by a professional (not at a Chrysler dealer). At the same time, a new battery was also purchased and installed. Since then, new alternator works...

I have an 04 WJ with the 4.0I6 my regulator for the alternator just went out and I am looking to go up on power output so I don't have the "dancing" lights I have been. I have read that I can replace it with the alternator for the 05 Durango with the 4.7l v8. Problem is I don't know which one to...

Hey everyone! Im in need of some help. Got a 2005 WK with the 5.7L and for the last 2 days my battery light was on, and while driving, voltage was only around 10.6 - 11.3 volts. I'm assuming it's the alternator. But then today, battery light went off, and while driving stayed around 14v or so...

Hi - I have 1979 CJ7 with a AMC 401 V8. I just purchased the vehicle and am upgrading the charging system, which i was told by the previous owner has issues, causing the battery to constantly drain. It has a delco alternator in it now, I have purchased a new powermaster alternator to replace...

I recently bought my 1974 CJ5 304 as a project/hobby to learn how to fix it. I began troubleshooting the wiring due to the engine not turning off when the ignition is turned off. Then I noticed the wiring wasn't correct on the alternator, voltage regulator and solenoid. I've corrected what I...

At 245,000+ miles and a weekend wash job that included spraying under the hood (I know, I know), Monday morning's startup was normal, but a half mile into a 55-mile one-way commute to work, I noticed a slight miss, and just figured it was a little dampness. Three miles later it starts knocking...
