Hi, I need help how I could fix my car. the other day I was checking my alternator. I disconnected the negative cable from battery to see if the car stays on. Unfortunately, it turned off. I put back the negative cable and I tried to restart it. it didn't do anything so I kept moving the key back and forward. To a point, the key began to feel loose. and now that I removed the key, the dashboard is still on. I don't know what to do. please help. there is the link :
