Simple fuse box fix?

Ok I just home and tried testing some things. Heres what ive got so far, Ive got power to the alternator, power to the starter relay, power to the top and bottom of the fusable link, power to both the black and red wires at the ampmeter . Cant seem to get a light on the firewall block of wires but im havent pulled it off yet since its so stuck and old. Heres a few pics so far.
