Sadly, you damaged your charging logic inside your system.

Often times when the MagSafe cord fails it can short out the signal line which then damages the charging logic. Review this Apple T/N to make sure you’ve got the correct MagSafe adapter and the cable & connector are both in good shape. I don’t recommend patching the MagSafe cable as you did here [|Apple Portables: Troubleshooting MagSafe adapters]

As to fixing your problem you’ll need to work up the chain starting with replacing the DC-In Board following this guide [guide|7660] If that doesn’t change things you’ll need to get someone to fix the logic board.
