Hi Sidney,
I don't think the fuse is in a fuse box. Rather, I believe it is incorporated into the wire between the starter and alternator.
I copied your pic above. I circled what I believe may be the fuse. Note: This is a 200-amp fuse. I am able to see the number 2 in the pic. Is that 200?
Also, to check for power at the alternator, you can use a voltmeter, a multimeter or even a simple test light. We just need to determine if there is power at the alternator from the starter. If there isn't, then the fuse is the likely cause. If there is power, we can assume the fuse is good and we need to check in other places.
As far as a test light, you can get one for under 10 dollars. I attached an example of one on amazon below. If you had that light, the alligator clip would go to the battery negative terminal, and you would probe the pointed light side on the wire you are checking for power. If there is power, the light would turn on.
Let me know if this helps or if you have questions. I'm here to help, so don't worry about asking questions.
Take care and let me know what you find.
Joe
