"Batt" recepticals on fuse box... No power.

[CJ_Chevy]

Hey guys,
another questions about my 79 c20.
i just redid all of my dome light and cargo lighting system and when i plugged it in to where it used to be on the fuse box, it would not work. it was plugged into one of the Bat terminals on the bottom right side of the fuse panel. i hooked up a volt meter from the terminals to ground and i got nothing, in any of the key positions. i wanted to make sure that my new wiring and lights worked so i tied the one orange wire for the harness to the 12v block under the hood to make sure it works, and it functions correctly. the cargo switch works, the dome light is on until both door switches are pressed in, and tuning the dome light on with the headlight switch works.

i checked my fuses and they all seem to be good. the only thing i found was that i had a courtesy bulb blown. but that wouldnt explain why my bat terminals arent putting out power. does any one know where or what fuse controls those 2 terminals? i believe the other terminal is for my cigarette lighter.

thanks in advance
