Ok- so I swapped to the civvy alternator for my 5 ton that is offered to us by @74M35A2
Installed correctly (I believe) but am having issues.
I made sure when I installed the belt was tight, so that isn't the issue.
With the truck running, I am showing 29vdc from the positive post of the alternator. I did **not** check at the batteries (doom on me... booo!!!)
My alternator guage was in the red. I was told to expect it to read low, so that didn't seem like an issue.

I let the truck run about 5-10 minutes and went to shut down and the "start" switch didn't turn the truck off. I used the fuel shutoff to kill the truck, then when I tried to shut the batteries down, it wouldn't turn off the batteries.
I used an inline battery disconnect I had installed earlier this year to shut power off to the truck.
The new alternator only has a positive and negative post. I did not hook up the small black wires, one of which is a small ring terminal and the other is the military connector. They are isolated and electrical taped to keep them from touching anything. I did check ground with my multimeter and was showing 0.00 ohms of resistance, so that's good.
Anyone have any ideas? I have a message out to @74M35A2 explaining the issue and asking for a call, but does anyone have any idea what's going on?
