So at first I had thought I just needed to jump my car due to an old battery. Got a new one and it did just fine until a couple days later then something started to drain it. Then I had changed out my negative terminal due to it being the original one from 2000’s and it started up again after that. It would drive fine after jumping it, I would take it for a drive about 30 minutes or so and come back home, shut the car off and almost immediately after the drive it would sometimes hold the charge or it would need to be jumped again. Lights would pop on the dashboard but car would not turn on. Now it’s not turning on even if I jump it and I’m not sure what to do from here. I have zero experience with cars besides driving them and can only explain the problem. Someone please help me!!
