Default 67 Electrical System went dead- need diagram

I was re-arranging the wires around my battery and the wires to my electric fan controller and after I was done I tried to run the car to see if the fan still worked OK. After a short start up and run (about 5 seconds) everything went dead. No solenoid clicking no lights, -- nothing. battery is fine. I disconnected all wires from the battery to be sure there wasn't a short smoldering someplace. I was not able to find any hot wires or smell anything.

My gut says there is probably a main fuse or a fuse wire someplace in the car that has toasted. Any ideas where I can find a wiring diagram? The car is a 67 Chevelle Malibu Convertable. I've had it about 15 years and since the restoration have never had any electrical issues with it.

Thanks for any help.

Pete

The pigtail off the positive battery cable should have a fusible link attached to it. I'm not familiar with the 67 wiring layout but on my 70 the pigtail/fusible link goes to a junction block on the rad core support. Check the other end of the fusible link to see if you have voltage. There is also a fusible link in the harness near the main splice. Look at the wiring diagram in the link below. Start at the battery and work towards the fuse block to see where you have voltage and where you don't.

Default Can I just replace the fuse wire with a "fused" wire

Is it OK to replace the "fusable wire" with an actual fused wire? If so, what amperagre should I fuse it at?
I just installed a fuse block for all of my accessories to replace a bunch of in line fuses which probably caused the issue in the first place

The fusible link can be replaced with a fuse, not sure what size, probably close to 100 amps. The nice thing about a fusible link is they don't go easily. A direct short on a fuse and it will blow almost instantly. Say you but a screwdriver or pliers in the wrong place, fuse is gone. Fusible link would survive that. It will go before the rest of the wiring starts to melt but can handle a momentary direct short.
