Truck Drawing Battery

[antig24]

I have a 95 Chevy 2500series pickup that keeps drawing down the battery. I put a test lite between the positive battery cable and the positive post of the battery, and it lites up pretty good. I have a large fuse block under the hood with small fuses such as 10 to 20 amp size and also some large ones such as 50 and 60 amp ones. I pulled all of the fuses and the only one I pulled that made the test lite go out was the 50 amp battery fuse which I guess makes sense. I know there is a clock in the truck that takes a small amount of juice, but I have tried two different batteries with the same results. The batteries do not take much of a charge after I drive it home from work about 20 highway miles, so the alternator must be charging them back up. Is there fuses anywhere else in this truck or does anyone have an idea? Thanks for any help!
