When disconnected, my battery will sit at around 12.8 volts. I tested the current draw by disconnecting negative terminal and then using the multimeter in series. It read -1.8 amps, which is a ton. I also tested the voltage after immediately turning off the car. The voltage drops quickly from 14 volts to 10.5 volts within 30 seconds, you can watch the numbers fall.

What could cause a draw this large?

    Yea, like another user said, I should have let all the modules power off before I did the test. My biggest question is why does it only happen in the colder weather.
