Ok, so I just got a digital multimeter yesterday to replace my aging but trusty analog multimeter. I guess I had the red lead in the unfused DC 10A plug in instead of the other positive lead plug in , which is where it was supposed to be. I was just going to take a reading of my battery volts and when I connected the multimeter my underhood light started dimming and I could tell power was draining. I immediately unhooked the multimeter and felt that the wire leads were hot to the touch. I used my analog meter and it showed that I had somewhere around 6-7 volts now in the battery where there was 10-11 before I tried to get the reading. I unhooked the battery and slowly but surely the batt amps started rising back up to around 10. What is weird is that when I reconnect the battery cables the battery drops down to the 6.5-7 volt mark.

Does this mean I screwed something up and now have a huge drain on the battery or do I have to charge the battery back up to where it was before I screwed up with the multimeter?

The other thing is that when I connected my battery charger to the battery with the cables installed in the car, I could hear the IAC functioning as if the pintle was adjusting itself. Should the IAC be doing this???
