Would you be willing to measure the outside diameter of the rib edges? I’ll measure mine and we can compare lol
I will look into this on weekend.
How to swap a high amp Dodge Durango alternator into your Jeep Wrangler TJ

I will look into this on weekend.
What is the correct voltage for idle?
I see that it is at 13.7V.
Shouldn’t it be at 14.5V or something?

That I know of, I’ve never been near 14.5v on the stock or current alternator.
I don't closely track it, but I'll see what it is right now.
It's currently bouncing between 13.8v and 14.0v in idle.
Note: this voltage reading comes from the OBD2 plug, so there's likely about 0.1vdc of voltage drop.
I am reading it with OBD reader as well. I see that at idle I get 13.6 or 13.5. On highway, when RPM is much higher, I see 13.9 to 14.0.
Never see 14V during idle. Maybe indeed this is the fact that I dIdn’t swap the pulley
I didn't swap the pulley on my Durango alternator. And, I've seen my voltage lower than what I gave you today. If you don't have problems starting or running your accessories I wouldn't worry about it (my $.02).
But I am curious what the stock pulley measurement is compared to what we are running (o.d. measured at the pulley ribs). I have a feeling the difference is only about a 1/8", but that's a guess and is something I'm interested in confirming just to know where things stand.
