TO start out, Ive had a few problems with needing to change out the battery terminal due to slight corrosion on the connection causing it to not start occasionally. Just been busy lately so I havent changed it yet. So I went outside this morning on my way to work and got in and it didnt' start. So I popped the hood got out and jiggled the terminal, tried again, nothing. So I removed the terminal and cleaned the connection and replaced the terminal. I heard a beep... beep.... beep.... beep... etc. come from the cabin. I got in and started the car fine. Then noticed the airbag light on. Tried disconnecting the battery all day at work and nothing it's still on. How do I go about finding out what's wrong and get rid of that annoying indicator light? THanks!
