Upgraded Alternator Discussion - Your Experiences

[jonheld]

Been running the OEM charging system for years without issues. Single battery system. Warn M12K with a bunch of other doodads.

Keep it simple. The more you add, the more failure points you introduce.

Yes, you'll run down the battery with a fridge after a few days, but that has absolutely NOTHING to do with the alternator because THE ENGINE IS NOT RUNNING.
I have an Ecoflow unit with a foldable solar panel that runs my fridge when I'm parked for a while.

The OEM Denso alternator has replaceable brushes part# 27370-75060 for around $20 from any dealer.

I have the @Delta VS upgraded alt its not a hard install. I run lots of electrical 200ah house battery and all the the things.

The big alt charges everything back up fast after draining the battery at camp.

If you haven't had any low charging issues then stock would be fine. Add a volt meter and watch it with all of your lights on and using the ham/gars radio and everything else. Then you can make an informed decision based on your rig.

This is insightful. You guys are super. I will look into replacing the brushes, and it seems my use case may not need the 130 amp alternator.

Revisiting this forum. Redline tested the alternator during some technical maintenance, and it is charging. I will be running the OEM alternator at least until it poops the bed!

This info in this forum is extremely helpful though for me and others.

After upgrading my wiring, I replaced my OE alternator with a Jaguar alternator from RockAuto. It was a drop in that required slight modification to the body of the alternator and the OE mounting bracket.

140 amps and works well to charge my dual batteries and other electrical items in the back. It actually did make my OE headlights brighter and we need all we can get.

IMO there’s no need for that upgrade!
I like the KISS plan keep it simple stupid
I run the stock alternator with the group 31 AMG battery.
It runs the ARB fridge, on board air, 10K winch + the light bar, and all the OEM stuff.
Never an issue can run the ARB fridge for 2 to 3 days in camp and still start the truck.

I run the same setup but a single group 27 and Engel with great results.

I run a 150amp alternator and it is by far one of the best upgrades i have done to this truck other than suspension work.....

Most of us aren’t running the dual electric fan set up that you are.
Plus I believe you have a lot of electronics in your rig so a bigger alternator is paramount.
