My battery is always running down. Have had Battery and Alt checked they are good. I have used a test light and have a definite power draw. Have pulled all visible fuses and circuit breakers but I still cannot find problem. IS there more fuses? If so where are they?

So when you put test light in series with batt term and batt it lights? If yes you got a big drain. If all is so try disconnecting the B+ to alt. Light goes out then alt diodes out defective. Here are eht fuse panels in the diagrams below.

I went back and pulled alt. Wire and light stayed on. I went so far as disconnecting alt. Completly with no change. I rechecked all fuses and breakers with no change. I have double checked everything being turned off? What can I be missing?
