Any details or maybe just link(s) to swap procedure, parts, mods etc? Ive seen a video of a 200A Humvee alt install with some basic modification. Only to read later in a post about needing to do something with the polarity protection as its only rated for 100A. And that was not done in the...

Does the 260 that is for the C7 engines work on the 3126?

Well the other alternator didn't have this issue. Battery’s in the truck tested 12.7 each after over an hour of rest. The two I pulled showed 100% after just a minute or two on a charger. And aside from being undersized the batteries are fairly new, dated August 24. The other alternator seemed...

So i’m pretty sure I got burned on this alternator. Now that I think back they told me it was a “take off”, i originally asked if the had NOS, and the reman, but foe this model they just had the take off. I would think they’d test it before selling it. Maybe im wrong but here’s whats happening…...

Went out for highway testing and it still threw the code. Same one, 1323. ECU volt high. Volt gauge seemed more stable overall, less volatile jumping around, but still jumping around constantly. Looking at the gauge this trip I realized some of my earlier figures were a bit off. I was thinking...

So I went out and disconnected all the batteries again and swapped in the voltage regulator off my reman alternator. Hooked everything back up and fired up the truck. Immediately the V gauge was almost rock solid around 28V. Before the V gauge would bounce around between 24 and 28v wildly...

Two issues I see there, first I dont have a load tester. Second is I'm not sure what I would do about the battery cables as they sit vs converting to two batteries. Here are photos of my current setup. Any ideas?

What would I have to do to switch to a pair of group 31’s? Any modifications and what about battery cable routing. Also is that something I can pick up at a generic auto parts store? Also I'm on 4 batteries currently, ive seen photos of guys who have 6. Not sure if that makes a difference. Was...

So I went and disconnected the exciter wire and started the truck up. Seemed fine at first except voltage was showing around 22V. Made it about 500 yards before trans started freaking out and dropping into neutral, I'm assuming now its getting hit with low voltage and cant function. So now I'm...

Well as tempting as a new FREE WELDER sounds I guess I’ll just swap the new voltage regulator over and report back. Do I need to disconnect all the batteries to swap the regulator out?

I think ill try and swap my regulator for the one on the refurb alt I picked up. I also found this video about the “exciter wire replacement for high/low voltage” and wonder if this is something I should look into at the same time… My truck already only has the E wire connected to the...

Well holy smokes, that didn't work out. Here’s the update step by step. Put it back together and started heading off the property to the main road. On the way out I noticed the volt gauge seemed much less erratic. Before it was a near constant and fast bounce between 26 and just over 28v...

Ok, interesting development. I was 2 bolts away from having the alternator out…had the long alt mounting bolt left holding it in place and the last connector on the alt I was about to remove was the 28V bolt. My wrench just tapped it as I was trying to slide it into place and what do you know...

Nothing loose on the polarity protection device/LBCD or anywhere else along the line that I can find. Guess im headed to the alternator swap unless theres anything else I need to check first.

Awesome, thanks. No battery disconnect on mine but ill go drop the spare right now and go back down the line from alt to batteries before I start taking anything apart at the alternator.
