Good info. side note. my Dad was an aircraft mechanic. I believe he said, back then that the civilian aircraft he worked on were 24v. When he was young he witnessed a coworker melt his watch on his wrist by 'tangling' with 24v cables / tools. That was the last day my Dad ever wore a ring, watch, neckless, anything while working on aircraft.
4.0 L usually also have ground wires / cables on the side of the engine behind the alternator. And sometimes by the rear of the engine by the transmission bell housing. Have heard of people having grounding problems in all of those places also.
i have a 99 jeep cherokee. same problem, intermittently shuts off, runs rough, a couple times just shuts down and wont start. everyone with this problem should jump the ignition switch red and blue wire. put a switch between the jump so you can turn it off and on. drive the car with the switch on and see if this takes care of your problem. if it does then its your ignition switch, not the key tumbler, but the switch box that the wire connector plugs into. about a $40 part. i went through a lot cleaning grounds, new coil, cap, and wires, checking wire looms and it ended up being the ignition switch. my problem was intermittent so i put the jumper switch on and drove for a few weeks without a problem before i spent the $ for the switch. hope this helps someone
Cool. Recent jeep had loose battery wires, but i had an older one that was doing this because the key chip was failing, a locksmith got me a new key and repaired ignition switch for about $35.
Ground the bracket that holds the relays and fuses, jeep liked to use aluminium rivets to hold brackets to the sheetmetal,over time the aluminum oxidizes and the bracket becomes a bad ground reference to any electrical part grounding to it ,this fixed my renix comanche, it wouldn't even start on hot days
@@josetrejo3427 no, haven't had the money yet. my TJ is just resting for a while. I will revisit all these comments when funds allow. thanks for asking.
@@tytt5349 Dude! I never really solved that problem. I replaced the entire ignition system, all the leads, the ECM, and lots of other stuff. I called every Jeep dealer within 200 miles for help and they all told me they couldn't diagnose a TJ because it was too old and they didn't have the equipment. I just dealt with it. It would stall, but it would start back up in a few minutes like nothing ever happened. I finally sold that Jeep, and I am glad I did. It had a ghost or something. Good luck with yours.
i was getting high voltage codes and stalling/rough idle (1997 Cherokee). i checked for vacuum leaks and inspected all the wiring pretty closely. I replaced a few simple things that made no difference. After i refreshed the grounds as described in this video, zero problems and the check engine light disappeared on the first drive.
My folks have a 1996 jeep cherokee sport 4.0 On those ground wire that are bolted down with a sheet metal screw🙄. Weld an grade 8 upside down skinny bolt and cut off those factory connectors and crimp on new ones then solder them and once their tightened down put dielectric grease onnthe contact areas. There are 3 ground wires on the passenger side engine between the fire wall and the distributor also repeat the prosses as I mentions above . it will have better ground connections 👍. I also welded a bolt in place of the far sheet metal screw on the gender well next to the battery of the skinny ground wires to anchor to
My 98 Xj has given me issues.i replaced idle air control valve, tps sensor, re grounded all ground wires, and it has been pretty much fine since.also spark plugs for the xj.switch then out never use champion or auto lite.either get Bosch plugs or ngk.the champion plugs and auto lites the electrodes are prone to cracking and will get in your cylinder and destroy your cylinder
I’m getting at intermittent slow cranck when starting. New starter and new battery...same problem. Gonna check ground wire. Mine is a 2002 grand Cherokee 4.7L
I'm dealing with a 2001 Jeep Cherokee myself and having a problem with it going into ASD mode and amongst a billion minor glitches that are going on with it no power on the driver side door windows what else it's a multitude of things that I'm dealing with right now on it mainly right now is trying to get rid of the auto shut down which I think the data link is being hooked up either it's not getting a ground or it's not getting a 5 volt reference and so it's not it's not sending volts out to it so it's not lighten up fun yay
Thanks for sharing. My 97 dies the same thing ,but also if I hook a corner hard. I am going to check the idle air valve and fuel filter ,but swear my tank is plastic so ryst and grit shouldnt be in there.
Keith Tomczyk Thanks for watching. I wanted to do video I was still having problems. Replaced cam shaft sensor several weeks back and problem has not occurred again. Might be worth checking.
My Jeep Cherokee is a 2000 4X4 right hand drive to carry mail on my rural route. I make it out to approximately same area each day before it starts stalling. Husband has to take off from work and bring my “back up 2wheel drive Jeep”. I had the coil pack replaced. Same thing next day. I will clean all the grounds this weekend. If that doesn’t do it I’ll beg for help from all Jeep Cherokee owners.
If you remove the battery while it’s running, does it shut off? My Jeeps rpm needle spiked while I was driving then shut off on me... moments later after I got it running I got on the highway and the Battery needle spiked to 19v ... the following day the Jeep did not wanna start... I checked all the grounds and fuses... I started the Jeep and disconnect the negative terminal and the Jeep shut off... so I immediately thought it’s a bad alternator so I replaced it.... installed it, but it still does the same thing... I’m not sure what it could be..
did you think about measuring ohms between the battery negative terminal and all the negative leads you removed? Would have saved you a bunch of time...
I have a 03 jeep Laredo 4.0 car stalls only on idle cold start is good until it acts like it’s up to temp then it starts misfiring and stalls at stop sign or red light dies also any suggestions bud?
Easy question: how do you remove the ground next to the battery? I just snapped mine trying to twist it off, and forums say it's welded. Just wondering where I went wrong.
@@johnagsmith2364 no it was not starting up by itself, what happened is that the key sign was puping up on the dashboard and the jeep will start for 5 to 10 seconds and goes off again
I see your still replying to comments I have a 2004 Jeep 4.0 and it stalls really rough but only when I first start the car(cold engine start) and after I run it for 3 minutes or so it starts running good... any help?
I can't help it man I don't mean to pick on you I'm a fellow mechanic too been working for about 15 years well 17 now on cars but I got to ask what did we learn LOL JK say don't get hurt man trust me a car will run you over that's happened to me so I'll calling the kettle black LOL

There are two more ground wires right next to the distributor. Great vid.
Wedding rings can burn a man in so many ways.
Absolutely 👍
True but it is a good way to keep from getting the clap or something ajax won't wash off 🧐

Jeeps are famous for ground issues. Check and clean yearly, and is a plus to put Vaseline on connections

Hey thank bro I have a 2000 Cherokee doing the same thing thank you so much...

Wedding ring incident happened to my dad on a speedboat. That was probably 30 years ago and he still has a scar.
Now you have a permanent wedding ring that you will never lose.
That's kind of the point of a marriage....

Did you cleaned the wires? And did you fixed your problem?

Sounds exactly like what mine does… just bought it and did a trans swap
Great video boss I got 03 fixed the issue
did you think about measuring ohms between the battery negative terminal and all the negative leads you removed? Would have saved you a bunch of time...
How do you do that? Just turn the volt meter to ohms and touch the negative and the ground(s) one by one? What should it read?
Crank position sensor?
I'm having the same issue with my 06 wrangler but I'm thinking that it might be more than just dirty grounds! But I'll give it a shot....thanks!
My ring went red hot almost immediatly 😂😂😂😂
Omg sorry to hear about your injury! Thank god I'm not married. lmao 😂🤣😂
Not only married but this is 2nd time around. Have great day
Should I disconnect the negative only while cleaning all of the grounds?
Hope you never get divorced, because that ring is permanent now.

Thanks buddy !!
Easy question: how do you remove the ground next to the battery? I just snapped mine trying to twist it off, and forums say it's welded. Just wondering where I went wrong.
None of the ones I removed were welded. All were bolts holding them to the frame. And really not sure about any would be welded to frame or to engine.
