The vehicle initially exhibited all these symptoms, (not starting, turning over, or getting any electrical power inside or out.). So, we jumped it and it ran fine after. We then turned it off and tried starting it again and it worked. The next day it showed the same symptoms previously listed. I’ve checked the battery and it’s still good, and alternator does its job correctly. What could possibly be causing this?

This sounds like a bad connection at the battery, I would remove the cables and clean the terminals. this guide can help you fix the problem:

Hi, thanks for a quick response! I can’t presently take a picture but will tonight. I used a wire brush terminal cleaner to get any buildup off the battery and cables, but still no lights inside or out or dash, and no sound when turning key.
