no electrical power

99 F250 PSD. Went to start last night it didnt want to start, turn the ignition off then back on waiting for the wait to start to turn off, went to crank it over and heard a pop under the hood and all the power went off, no power at all. Is there a main fuse that could have blown? Thanks.

Check fuse #20 under hood in main box=50 amp fuse.
If good,there are 2 fusible links upstream of fuse and are gray wires and links are "J" and "A" links.
These power switch,starter,etc.

I have checked the fuses none are blown. I cant seem to locate the fusible links. Any help would be greatly appreciated.

They are inline between starter motor relay and batt. junction box-should be red in-gray out.
Do you have power to fuse 20 on either side to ground with fuse out?
