You could have blown the starter solenoid and/or starter motor.
Once in shop class. I was remove/replacing a starter on a car. Forgot to unhook the battery ground before lifting the car, and was unhooking the starter leads when the end of my rachet hit the ground lead while I was disconnecting the hot lead. The light show was pretty impressive needless to stay. Ended up welding the inside of my rachet, blowing up the solenoid and burring up the starter drive motor.
Question with BOLDNESS, the very existence of God, for if there be a God, he would rather honest questioning, over blindfolded fear.
