Ok, kinda lost for where to start on this issue.

1. Installed brand new battery (car was sitting for 7ish years) died on me after driving about 3 times.
2. Tested the alternator and it wasn't charging the battery.
3. Replaced the alternator (wow worst placement I have personally dealt with).
4. Tried to start if after charging the battery a bit and dash lights come on but it can barely crank.
5. We try a jump box, turns out the jump box is half dead, same results as step 4.
6. We connect jumper cables to try jump it off my other car.
7. On key turn we hear an audible click/pop, all dash lights go dark. Will not crank of light any dash lights now.

This is where I am now. First thing I checked were the maxi-fuses by the battery, they're all fine, tested them with a multi-meter. Double checked the battery cable, its very snug. Should I start hunting down grounds now? Anything else I should check? Thank you!
