Have the battery load tested, the alternator checked for proper output and a parasitic drain test done.

I would start there

The battery is bad. When I touch the positive to the battery it sparks when its off. Like something is dragging power out of it.

Replace the battery first to see if the issue still exists. The spark is powering all the modules. Stop doing that as voltage spikes tend to kill modules
