I figured it's because I'm using a smaller battery (miata) and there is a stupid chance that the hazard lights may have drained it. So I got my brother to jump start it and it fired right up and my safc2 showed 14.1 volts. As soon as we disconnected the jumper cables, the voltage started dropping slowly. Within a minute or 2 it was down to around 9 volts and I just shut the car off because it was on the verge of dying anyway. Again we jump started it and same thing happened, the volts kept dropping until the car died. Finally I decided to try to move my car into a parking spot before the car would die. Once the car was in the spot I looked at my safc2 and it was holding a 14.1-14.2 charge. Um..wtf?
Now when I drive my car the voltage fluctuates. If I am driving, the volts stay between 13.8-14.2. For some reason when I slow down to a stop the volts drop to 12.8-13. I've also noticed that if I shut either side door, the voltage will drop down to 12.8-13 then come back up to around 14.
I've had to jump start my car 3 more times this week. Is this an alternator issue?
This may be unrelated, but my automatic seat belts have been acting funny lately too. They cut in and out a bunch of times while going down.

i think you mean another alternator thread. make sure the alternator fuse is not blown. . your seatbelts are experiencing a lack of voltage
