Electrical issues,

[Cnordy]

Hi, I have a 72 blazer that is almost finished and looks great after a body and interior restoration , its all back together except for an electrical issue I have.

Here goes, I am installing a stereo and I was hooking up the memory and power from the ignition and all was working, then I un hooked it and ran my wires, hooked it back up and discovered no power to the stereo And then discovered no wipers and blower fan for the a/c-heater ,

Replaced two fusible links in the front, replaced the relay for the blower behind the glovebox, all fuses replaced and seems like the complete fuse block is dead..

What am I missing, everything worked then all of a sudden it don't,, any ideas out there.. I have a horn, lights work ,Truck starts right up, something simple I hope
