Voltage problems, cutting out when hot

What the heck is that?
A CS116 or something?
What's the rotor draw on that thing?
And 0.4 Volts ripple with 2 Volts acceptable?
I don't know what that's for.
Maybe one of the other guys here knows.


And did you follow what @67Dart273 was posting about with the current vs. voltage?
It's the key to troubleshooting with voltage drops.

If not, or not sure, take some time to study this post.

It’s the factory replacement alternator for a 1997-2001 Dodge Ram. It’s just a new replacement of what was on the truck I pulled the engine from.

It’s a 116 amp denso with 2 pin plug. I have the two field wires running to the two pins on the alternator.

I can’t find anything on these alternators, if they are internally regulated or not (I do not believe they are?) and

I’ve read elsewhere that hooking it up this way works with the factory voltage regulator but if there are other opinions I’d like to know what you think.

Again, I am going off what I have done in the past as I haven’t been able to find anything about running this exact set up. (Magnum motor/serpentine accessories and original wiring/ac/etc

And I didn’t notice the post about voltage vs current but I will go over the High Charge Rate and troubleshooting posts now.
