Battery Sparks When Connecting Negative. Cable to remove battery it sparked. I believe the cable from the negative of the auxillary battery was still completely disconnected from everything at this time but i cant be certain anymore.

Small spark when connecting negative battery cable to terminal. Then disconnecting the positive terminal on the battery. The main fuse to the car may have burned up when the battery sparked causing all power to be lost in the car.
When I try and connect the battery terminals a few sparks will shoot then the wires get hot.
Installing new battery so I dont have to keep jumping. Everything went great until the very last step. Shouldnt be enough to cause sparks with just the cables between the battery and the panel. Installing new battery so I dont have to keep jumping.
