I know some of the guys who are using winches frequently run the idle up while winching. I am sure it is to get more JUICE to the battery(s)-Winch during usage. I hear they draw some amps. That is next on my Mod list are bumpers and winch.

You do need to add or upgrade the wiring from the alt to the battery which is usually the place the rest of the jeep gets its power for the simple reason that when lead acid batteries are even slightly discharged (like starting) will take all the amperage the charging system can give until recharge has occurred. It is called in rush current this may be for just a few seconds or longer depending on the how discharged the battery is. If the wire from the alt to the tie in point is to small then some not to pleasant things can happen especially if the battery is deeply discharged.

Check the part #'s at the website I bought mine at and see if your 2.5l is the same.
Here:
http://storesense1.mysuperpageshosti...ail.bok?no=476
vs.
http://storesense1.mysuperpageshosti...ail.bok?no=697 for mine. So depending on the years. Check yours there!

So for those that did an upgrade did you get a larger fusible link also? I did the 04 Durango alt upgrade yesterday, went to change the charge wire and came across the fusible link. Is there a larger one from Autozone as well?

Has anyone had any experience using the Mean Green alternator as an upgrade?

I found a 175amp in line fuse at Autozone and made my own fusible link out of 2 AWG cable.

Edit: No such thing as a 4.9L 04 Durango, I'm assuming whoever posted that earlier meant 4.7L.
Upgrade for a 1998 Dakota/Durango 360 would bolt in to a 97-03 TJ 4.0L.

I found this: https://www.dcpowerinc.com/fit/1998~...42-180-hp.html

$50 cheaper than the same upgrade specifically for the Jeep.

There's also a 270A alt on there but it's $600...crazy.

The 136A alt out of a 96-98 ZJ, Durango, 1500 PN 56027913 will fit the 2.5. The difference from later years is the regulator. On 97-99 the regulator is external and 00+ the regulator is internal. The 160A alt mentioned for the later years has an internal regulator and is not a direct swap in. It could be used but you'd have to rewire to use the internal regulator. The higher 175 amp alts from Load Boss are rebuilt from the 136A alt. You can get a local alt shop to rewire your alt for a higher amp if you really want higher or buy one already rewound. The 136A alt 56027913 (NOT 56027913AB, it's internally regulated) runs around $40 from a junkyard.

For my 98 w/ 4.0 : Autozone part #13387 136amp, is a DIRECT FIT. No changes are needed. This is an option for 1998 Dodge truck/Durango w/ 5.9 V8. Price was $147.00

For A 2003 w/ 4.0 : Autozone part #12328 160amp, is a DIRECT FIT. No changes are needed. This is for a 2004 Dodge Durango w/ 4.7 V8. Price was $121.00.

As I mentioned, for a '98 and an '03, these were direct fits and a great upgrade for the money spent.
The wiring connections for the field coils were the same? I know the ND alternators use M6-1.0 B+ studs as a rule, but you're right around the split where they went from two M4 studs for the field coils to a funky two-wire plug instead...

Please confirm - I'll use it to update my donor list...

You have the right idea.

What I would do is get an upgraded alternator for a Durango from these guys...https://www.dcpowerinc.com/fit/1998~...42-180-hp.html

Some of the bigger winches are drawing 400-500amps on full 5-6 ton pulls on the top layers of cable. A popular mod is to use a hand throttle to raise rpm to spin up the alternator for extra juice.

What if you do not upgrade the wiring? Can anything bad happen?

Yep, if you have a load on the circuit then the higher amp will fry the wire. It only makes sense, you upgrade the power supply, and you upgrade the wire. Don't want to cause a fire do you?
