Intermittent no start
So i just put a remanned alternator in my truck (99 24V NV4500) and im not getting any power from it. Everything is installed correctly and the alternator/batteries are good, but the truck only starts intermittently. As far as i know everything is wired correctly, never had an issue until the past week. I have nothing on the voltmeter and when the truck is running, its only running off the battery.
When i go to crank it, it does nothing, like theres a lack of power.
Both batteries and the alternator tested good, the starter was replaced in december. The truck starts and runs just fine, but its gotta be running off the battery since it dies if i disconnect one.
I checked and replaced the 140amp alternator fuse. Battery voltage went back to normal and the truck started right away. Let it run for a few minutes then shut it off and went to start it again. Same thing, voltage at the low end and wouldn't crank.
Any ideas?

Check for battery voltage at the field wire Dk grn (14ga) on the alternator and check for voltage at the larger charging wire (8 Ga). Below are the schematics looks like there is a 140 amp fuse also in the Power distribution center box (PBC).
