Location of Alternator Fuse/Link

Thanks, that helped me to find the fuse link. I tested it and it is good, so are all the fuses. The problem must be where the black/orange wire transitions to the yellow wire. Thanks for the speedy reply, it got me on the right path forward.

I had voltage at the alternator on the main terminal where the black/orange wire attached. I didn't have voltage on the yellow wire that went through fuse 17, though the fuse was good with the key off and I did have voltage on the green wire with the key on. I eventually took the truck to a mechanic who determined that the alternator was bad, replaced it and changed the serpentine belt because it was developing cracks. He told me that despite what I had read online, the circuit operation was the exact opposite. The yellow wire was supposed to have a voltage with the key on and if the alternator was bad, the green wire would then have a voltage to illuminate the Battery light on the dash. It was too late to test this when I got home but I will in the next couple of days Thanks for your help and following up.

With the new alternator, I checked the voltages at the alternator plug and they were like the mechanic said. With the key on, there was now voltage on the yellow wire and no voltage on the green wire. I guess you can't believe everything you read online. Thanks for your assistance!
