Low voltage battery, new alternator and still not charging.

Hi Ram community. I need some help.
I own a 2015 ram ecodiesel with 108.000 miles
A few days ago. I was driving back from work and stop for a cup of coffee, 10 minutes later got back on my truck and the low voltage battery came on, a 1/4 mile from home all lights and gadgets went crazy and the truck shut off, the battery got completely drained. Bought a new battery and it got drained again. I replaced the alternator and exchanged the battery for a new one and same thing battery got drained and it reads low voltage battery again. The alternator has been bench tested .
Please i need your output. Thank you

Check over your fuses, grounds for the motor, and wiring from alternator to battery
