Battery Died When Turned On Passenger Air Bag...Help Please!
 

So I was driving my 1999 Mazda B2500 today with my wife and noticed at a stoplight that the passenger airbag was off. At a long light, I cut the car off and put the key in to turn the airbag off. When I went to start the car again, nothing happened...no clicking, blinking lights, nothing

I was able to jump the car and drive the 15 min home. The battery appears to now be dead. A few lights flicker, but nothing happens when the key is turned.

Does anyone know why turning on the airbag would suddenly kill the battery? Anyone have any ideas what is wrong?

Thanks
