What is your question?
I have a 2010 Dodge Ram 1500 V. 85.7 rear wheel drive. I have replaced the battery. The battery is brand new. The alternator is good, but the alternator is not getting a signal to power the battery I was told. It's something underneath of the fuse box, but don't know for sure.

Hello, Dave here, contributing to RepairPal and providing expert advice since 2010.
I do not know of any part under the fuse box that influences this system's charging.
Your alternator produces adequate amperage and has the voltage output regulated via the powertrain control module (PCM). Desired and actual output voltage is measured and then regulated as needed.
What testing has been performed to check alternator output in voltage or amperage?
Has the replacement battery been tested to ensure it is fully charged and able to accept a load?
If your charging system is putting out proper voltage and amperage and your battery is good and accepting load and charge - all would be well. Please share testing and what is missing?
