[QUOTE="CplCuddles, post: 8653928, member: 663649"] Ok so update guys, I haven't figured out what has been the issue so far. I haven't been able to clean my throttle body and MAF Sensor, but I don't honestly see how that would make my battery die overnight tbh. I just got a new job finally so I should have income coming in to start actually fixing issues, but I still have to figure out what the f'ing issue is. Today I came out to my Tahoe after the night and it was sitting at 9.9V, I had to get it jumped for it to start. As soon as it started straight up into the 13Vs and when I started driving stable at 14.6V. I tested Voltage while the vehicle wasn't on and it said 10.1 with my Fluke DMM(My in-car VM was set with a cheepo dmm), at the battery and Alt. I did a parasitic draw test by disconnecting my neg batt terminal and using my dmm in amp mode and connect the - batt terminal and the negative hookup. Upon doing this it jumps to 1.7Amps for about 2 seconds, drops to .7Amps, then down to .16Amps and finally rests at .06Amps. I figure that is due to the computer etc etc. So if I have no current draw... how tf is my battery dying? Pics follow...
