I was jumping my daughter's 2001 Saturn(dead battery) and when I was adjusting the negative battery cable, it sparked, the locks locked, locking me out. I had the cops break into it, and then the driver side lock stopped working.\R\nThen, the car wouldn't start so I put in a new battery. Started right up. The next day completely dead. Attached a battery charger to it today and accidently put the negative charger on the negative terminal. It sparked and the doors locked again. Opened the car up with a key and now iit's charging with the negative chaging cable correctly on the frame. Any ideas/suggestions?

Hi mjmpyramid. Welcome to the forum. Normal procedure is to connect the positives of the dead car and the charger or donor car together at the battery posts, then connect the negatives together last. If you're using another car for a jump start, the recommendation is always to make the second negative connection to the engine or body, ... Someplace away from the battery. Batteries give off hydrogen gas which is explosive. The two cars will have different system voltages so there will be a small spark when the final connection is made. You want that to be away from the battery.

When using a battery charger, it doesn't matter if the negative cable is on the battery post, the engine, or the frame. They all go to the same place. Just don't turn the charger on until the final connection is made. The advantage, again, for not connecting right to the battery post is to keep potential sparks away from the battery.

Of bigger concern is why is the battery going dead overnight. Also, sparking at the negative battery cable when you wiggled it suggests that connection should be cleaned and tightened. A dirty connection will also prevent it from being fully charged while driving.
