Battery Drain
Hi everyone. New to the forum. I have a 2002 Chevy Suburban with a killer parasitic drain on the battery. I've read all the thread in this and other forums and I'm still stuck. I can't narrow it down to just the BCM. The only way to kill it is to pull the under-fuses marked TBC, RADIO, and SEO1. But none of the three is a consistent portion of the draw. It is driving me nuts. Anyone out there with some tips?

Welcome to the forum...
Have you pulled other fuses to help eliminate possible draws?
Made sure no vanity lamps are staying on? no under hood lamp on?
Nothing plugged into any power outlets..
check the trailer harness for any shorts..
Pull relays a few at a time...
Try disconnecting the battery and checking it by itself the next morning to make sure its not the problem...
Try disconnecting the alternator...(over night)
