The other day I tried to start my car and the battery died. Then I jump started it the other day and it ran fine. I drove to work and it started just fine. The next time I tried to start the car there was no electricity at all. Today I started and let it run to hopefully recharge the battery. When I turned it off to see if it charged there was still no electricity. I even tried a brand new battery but there's still nothing.

 

Check the connection inside the fusebox on the passenger side wheel well, I had a problem once and the battery cable was tight but not tight enough and if I turned the key on there would be power but when I went to crank it it would arc and everything would go out. Definitely sounds like a connection problem... That or grounds!
