Rub some dirt on it, it'll be fine.

I know whats wrong with it...aint got no gas in it.

No one ever said you do things half ass, good job getting that mud thoroughly distributed.

I wonder since these alts are also reverse mounted if that is not making things worst and more susceptible to problems.

You need to make your self some sort of mud flap to cover that thing

LOL - great one. If ur gonna do it........ put your all into it.

You beat me to it - took a few seconds but then I realized, hey, most alternators have historically cooled from rear to front. The fans are pullers, not pushers, cool air enters the rear of an alternator.
Now I need to go start my truck, open the hood and double-check but if it's a normal flow alternator, being mounted "backwards", this thread may have just found the reason for this, and a prior failure. Not water at all - MUD

Other failures have not been due to fording water, or splashing water - go back to another fight someone had with Jeep/dealership - it was the mud. These aren't advertised going through mud and splashing up chunks.
At least in this case, the OP says "he broke it" and wasn't fighting "not my fault" like some would.
This whole thing makes me laugh a bit - not at all for asdgs's problems - not at all, but he's exposed why this is not a warrantable thing like some insisted even without facts.

And for finally exposing the REAL reasons for some of these failures, we should thank the OP. This makes me even more determined that a certain other party was likely not entitled for warranty repair. If you plug your radiator with bugs, seeds, and mud and fry the engine, is that the fault of Jeep?
Water had no role in this other than the medium by which the mud was applied to fill all of the cooling holes and vents (not to mention the chunks and grit tearing at the windings)

Mudd was a problem decades ago and is still a problem, it seems...

WTF........did you take it out and played mudball with it? I've never seen a alt that plugged with mud before.

Before I once again say something stupid - are diesel alternators different? I ask because the gas version has a black cover over the rear, which in these is the front, if that makes sense..........
I mean, there's little room to pack mud in there with that black cover shielding the front, I mean the back that's facing the front........

I found something interesting about these - they aren't smart alternators. It makes sense looking at the wiring diagrams for other Jeeps - but I thought maybe these were different somehow. It appears that it is the PCM actually having full control.

From the configuration search I did inside my own truck, with 240 amp system -


E-Shifter present: Yes
Automatic transmission type: ZF 8-Speed
Shift Feature Autostick / Electronic Range Select Status: Autostick Present
Teen Key Feature Present: No
Surround View Camera Present: No
Full Speed Range Forward Collision Warning Plus System: Yes
Type of adaptive Cruise Control (ACC) system present: ACC with stop
Air Suspension Control Module (ASCM) has Suspenion: No
Air Suspension Control Module (ASCM) has Active Damping: No
Transmission Neutral Hold Feature Present: No
Red Key Feature Present: No
Active Blind Spot Present: No
Axle Locker Configuration: None
Transmission Equipped: Automatic transmission
Park Brake Type: Mechanical Park Brake - Hand or Foot
TPMS Configuration: Logic 1 NHTSA Enable Warning
Smart Alternator Present: No
Hybrid Type: None
Terrain Switch Bank Module (TSBM) Present: No
ADR Feature Present: No
Active Grille Shutter (AGS) Feature Present: No
Temperature Display Resolution: Half-Degree C
PTC Present: No
Glovebox Control Present: No
Motor on Caliper Type: Not Present

So either the programmers have it wrong, or these truly are more basic alternators.
Only the shop that worked on the one in question here could determine that.
This makes me even more determined to get my hands on one personally.
I find nothing indicating these in particular are smart, on the flip side, I see indications that they are not.

Good and bad news. first the bad. the alternator arrived damaged, but still works. Good news. the part is OEM and works like a champ! im up and running boys!!!!!

Bravo! Glad it's working. Looks like an unimportant or at least non-critical area broke, thankfully.

If you ever trash another and don't need it as a warranty thing, I'd be interested in getting one in hand, and I'd send it back on my dime.

I am thoroughly amused at your ability to clog that thing up so good. Congrats on being the first to own up to such an amazing job, ha! Pay to play I suppose.

I suspect he studied up on it for a while, books, online classes, checked the viscosity of the mud, calculated the correct entry speed, and went for it.

For the amount of technical knowledge I have you would think I did that, but in reality….I wanna do hood rat things with my friends is what popped in my head.

Oh, yeah, I can absolutely relate. Gee, that looks like fun, they're doing it - I"m going for it.
I have some parts on the shelves in my shop that I know better...... you know what I mean.
Your attitude is great - you broke it, you owned it, you fixed it. (and had fun doing it)

For anyone else that needs this. The alternator has one bolt that requires a External torx or you can remove the fan shroud like I did. Warning about mud it was concrete and everywhere. I mean this happened a month ago and I’m semi clean engine bay. Also the signal wire to the alternator requires a pick to raise the lock and slide it off. I learned the hard way.
