My Jeep's OEM alternator goes BAD!

Coming back from Mexico my voltage meter goes up to 17 volts! I lost the power steering and my high voltage alarm goes off on my Redarc system!! Thanks to Jerry from ‪@shiftautowerx‬ we contacted Apex High Output Alternators to do this important upgrade. I cannot be more happy with the end results.

Great info video. I think Apex learned a thing or two as well. So you were able to pull the Apex housing apart and transfer the “guts” into the original alternator housing? Genius! One good thing is where the unit is mounted on the 392, you didn’t have to dig deep to get to it. 👍

[@OVRLNDX]

I sent to them the original unit and Apex did the transplant! 😁

[@jrfuentes2688]

Great instructional video and really appreciated showing the issues and how they got resolved.

[@OVRLNDX]

Glad it helped!

[@stevetubo5531]

Great job Marco. I am glad you got your Jeep fixed up.

[@OVRLNDX]

Yes, thank you

[@pch-395]

Great video, informative and displays all your various talents!

[@OVRLNDX]

Thank you kindly!

[@JesseRizo]

Great video 🙌

[@OVRLNDX]

Glad you liked it!

[@leemen]

Great video. I’ll check out that alternator. Valuable info!!

[@infinityoff-road]

Glad you got it fixed! Thanks for the video!

[@OVRLNDX]

Glad to help

[@EFlo2000]

Thanks for the information and posting the video.

[@OVRLNDX]

You bet

[@anthonyarmijo]

Great job and thanks for the video and information brother.

[@OVRLNDX]

You bet!

[@markperza384]

Glad everything worked out!!

[@OVRLNDX]

Yes! Thank you!

[@charlesquarto7474]

Great video Marco! I was looking forward to hearing about your experience with Apex and how everything went.

[@OVRLNDX]

Thank you! Soon I’ll be doing the second part which is the wiring upgrade

[@patandjessicasjeepadventur3227]

Awesome Marco

[@RocklanderUSA]

Hola Marco, sorry to hear about the alternator. I’m glad you were able to resolve and install a new one. I have the 2021 JLUR with V6 Etorque but it has no alternator, it just uses a little motor instead to charge my Optima Yellow-top battery. Thanks for the informative vid. Good to know for when god blesses me with a 392 one day. Safe travels amigo! -Ryan

[@OVRLNDX]

Thanks, you too!

[@jr_jeep4470]

Marco, thank you for the share, I’ve been debating on the alternator upgrade why I’m not is upgraded with you with power options last year. I had an issue which I think was alternator related. Keep up the great work.

[@OVRLNDX]

Thank you!

[@TheGreekbull]

Good info especially if I ever run into this with my future 392!

[@OVRLNDX]

Right on!

[@peteacevedo3411]

Good Job Marco

[@OVRLNDX]

Thank you

[@fscottgray9784]

Good call on the upgrade. I failed to order the dual altenator setup on my Power Wagon and really wish that I had now.

[@OVRLNDX]

Thank you

[@JEEP-N-DIRT]

Just realized you also mentioned it's running consistently at 14.4 volts? The JL's generally have fluctuating voltage due to our "smart" charging systems. Is there something different with the 392 vs all other JL's in terms of charging circuit? Again, just curious?.

[@OVRLNDX]

Same smart alternator as JL’s! The upgraded one is not a smart alternator

[@danpayan9468]

Auto parts are ridiculously expensive regardless good job Marco

[@OVRLNDX]

Yes! Thank you

[@jimsatterfield7454]

Marco! Thanks for the vid and the info 👍 I was just at Jerry's shop earlier in the week getting some exhaust work done on our JK and I know where your new serpentine belt is 😅😅😅 Jerry wouldn't let me hold it hostage so I could get a chance to shake your hand. 😅😅😅😅 Be safe buddy! Jim S.

[@OVRLNDX]

LOL! I need to go pickup my serpentine!

[@rubiconadventurewithscotty3258]

Huge power needs - High current alt !

[@OVRLNDX]

Indeed! Now, a Big3 kit

[@shekharmoona544]

Marco: Mo powa bahbee!

[@dougcampbell4818]

I just ordered the 410amp alternator from Apex. Mine failed on my 2021 JLU ecodeisel.

[@OVRLNDX]

Awesome! You'll be happy

[@dieseltalkwithtonysalas8725]

Question Are you using the factory output cable on the alternator? Same gauge?

[@OVRLNDX]

Waiting for a Big3 kit!

[@joecerda630]

Saludos Marco...my buddy saw you at Anza last weekend...you make a video?

[@OVRLNDX]

Yes I do! Working on it!

[@johnmcvey2059]

So with the new alternator putting out more power did you up size any of the wiring?

[@OVRLNDX]

Just ordered a Big3 kit for that!

[@vdub5818]

So I guess by going to this alternator it no longer has a "smart alternator"?! That's actually a great thing and if that is the case no way will I go with an oem replacement when mine inevitably fails.

[@OVRLNDX]

Correct!!

[@spencermorrow2899]

Get a serpentine belt tool I just recently bought the Icon one from harbor freight haven’t used it yet but right now it’s under $100 as I type this comment. And maybe buy a second one to keep in the Jeep plus one at home

[@OVRLNDX]

Awesome! Thank you for the tip!

[@jameshenderson9228]

Dag gone.... now I found something to drop money on..😂

[@OVRLNDX]

LOL!

[@markrigney4372]

So the alternator was fine you just put too much load on it with the four batteries you mentioned if not the fifth auto/stop battery.

[@OVRLNDX]

I believe it went bad because of that. Fortunately the 392 doesn't have that aux battery nor the on/off system

[@JEEP-N-DIRT]

Marco, great story but very confusing based on how are JL charging systems is "supposed" to work, or at least as we've all seen. You mentioned all the load you have with multiple batteries, but correct me if I'm wrong. We're unable to connect "other" batteries to our system like in the old days hence the reason for using systems like red-arc etc... That said, since the systems are DC-DC charging and there's a separate system i.e. Red Arc then you're alternator should never see anything other that what the overall (fluctuating) charging load is. Not sure if you were implying that the extra loads caused the alternator to go bad or ?? Seems odd because the Red Arc (if functioning correctly) would never let your alternator overload (in theory). Just curious?

[@OVRLNDX]

Well the RedArc system went in safe mode when this happened. Same thing happened with the trailer’s Redvision system, I did noticed in Baja that trailer was not charging. I think the alternator was giving up since December

[@JEEP-N-DIRT]

@@OVRLNDX Ahh. That makes sense. Thanks for the reply. I'll be monitoring mine closely.

[@turbojunki]

How many miles are on the 392 now?

[@OVRLNDX]

55k !

[@CJ-rk5eg]

It’s TOO early for an alternator to fail. Very disappointing.

[@OVRLNDX]

I agree.

[@scottymac5174]

Alternators/electrical can be a strange thing. I had a new 1986 Nissan PU back in the day. I had the stock OEM alternator gp out under warranty. Had a new OEM alternator installed. It lasted a month. Then had a 3rd OEM alternator installed and it went to 275,000 miles;.
