Yesterday i was disconnecting the wires from alternator using a 10mm wrench and i forgot to disconnect the battery and it started sparking. so i disconnected the battery and then did my thing. hooked it right back up the way it was before and now when i turn the key to the on position there is no power. the battery is charged and i looked at the fuses under the steering wheel and under the hood and all were fine. wth is wrong?
