I had a bad air conditioner compressor that caused this same problem. It had almost completley seized and gave the car some real trouble starting. The burning smell I had was caused from the belt rubbing around the seized pully.

You need to get your test equipment checked. Your battery will not survive nor will the car start with those voltages. It needs to be about 11 to start. The terminal voltage should be about 13.8 when charging.
