Yesterday I drove it to my aunts, got back in it to leave and the battery was dead. I thought maybe I had left key on. So I jumped it off with another vehicle. My voltage gauge was where it was suppose to be. I get the battery and alternator tested, battery was good but alternator was bad. So I replaced it and now I have to have it jumped off to start it. After it’s running I unhook the jump cables and leave it running cut it off and try to start it back after letting it charge. And no lights on dash come on, like it’s not getting any power at all.

When you jump it, are you connecting the cables to battery positive and negative? Or battery positive and frame? Because if you have a bad ground between your battery and frame, you are essentially replacing the bad ground with the jumper cable by attaching it to the frame.
And either way I would ensure your battery posts and clamps are tight clean, and free of corrosion.
Yes, jump it red to red and black to black if you can. I suspect a bad battery or connection. I had my ex's battery out of her Silverado tested at AutoZone 3 times. Failed, passed, and failed again. So there's that. I'd buy a cheap multimeter, let the engine charge the battery by driving around the block several times, and stop it at the driveway. You should see around 12 volts at the cable connectors. When running, the voltage should be MORE than 14ish. If voltage is good when running, your alternator is good. If it's way less than 12 when not running, I'd get the battery tested somewhere else or replace it if it's more than a few years old.
