Hey everyone. I have a 1985 k5 and lately the battery has just been draining nonstop. I checked for a parasitic draw with the multimeter and I’m pulling 11 amps while the truck is off. I started pulling fuses to see if I could get the number to drop back down, but after removal of every fuse the number stayed the same. Do y’all have any idea what could be pulling power, or something else I could check?

Disconnect the big wire at the alternator. See if that helps.
Also make sure your dome light is not the draw while door is open. pull the courtesy fuse or the bulb

11 amps is huge! Where are you measuring this at?
If you have power window then maybe a window switch is bad since they draw about that much. But then again you say that you removed all the fuses. Sounds like someone added some accessories that aren’t fused correctly and shorting out - maybe a stereo, lights, trailer wiring harness, etc. The alt is a good start as suggested.
