Today, I was using the cigarette lighter to blow up a tube. I had the engine running while I was doing this. All of the sudden the motor stalled. I turned off the tube inflator and went to restart. But it wouldnt turn over. I checked the battery and the negative terminal was very very hot. I let it cool and went to start it again, but still had no luck. i dont think it is getting any spark. I hear the fuel pump working but it wont fire. Please help! I cant see anything wrong like disconnected wires or blown fuses. Thanks in advance.
