Well the two inner spades on the switch are on a different fuse .
In my FSM 1973 book
the -Map,glove,license,sidemarkers,tails,cigar,park are on 20amp fuse cavity 4
Check to see if you have 12volts on both sides of all fuses , the old fuse holders spoil real easily .
Did you confirm you have 12 volts on one of the inner spades?
