I have no wiring diagram for the car
There are a lot of wiring diagrams online, if all you care about is
installing a stereo or alarm.

says the starter wire is yellow, if that helps.
In that direction, you might look under the dash, below the steering
wheel, for any signs of an aftermarket car alarm installation. They
often cut the starter wire and splice it to wires from the alarm box;
the alarm box has a relay in it so it can stop the starter from running
if it wants to. If this added wire is grounding out somewhere, it might
be blowing that fuse.
If you live in or near the big city, the public library (often just the
main branch) may subscribe to the "Mitchell" auto repair manuals. These
are the ones that independent shops subscribe to; they are the closest
you are going to get to a factory manual without paying factory-manual
prices. They are much better than the typical Haynes, Chilton, etc.
The catch is that they don't circulate; take some change for the copier
(or a phone/camera to take pictures of the pages). They may also have
some online manuals, but print a test page before you print the whole
schematic; some of the earlier manuals were scanned at as much as 10 dpi
and you flat can't read the diagrams. Also, take a turn through the
regular stacks as well; sometimes they have real factory manuals sitting
on the shelf. Again, non-circulating, but handy.
If you get really stuck, the Haynes manual you want is #24071 at your
friendly local auto parts store. (The headline on the cover is Chevy
S-10 and GMC Sonoma.)
but I?m thinking that 12V must go from the 12V bus, through this 10
amp crank fuse, through the ignition switch, then possibly through a
relay, and then to the solenoid terminal on the starter.
Usually the ignition switch has one or two big feeds from the 12 V bus
and everything else is "downstream" of that. This image is for a
different problem on a '97 Bravada, but it shows how the crank fuse
gets power (far right of diagram):
