Hi,
Don't worry. We'll get it figured out.
Interestingly, that fuse is for the indicator light (alt-light). I need you to check some things for me. First, do me a favor. I need to know the 8th digit in the VIN number of the vehicle. There are different 4-cylinder engines that were used. I need to make sure I'm looking at the correct schematic.
Next, does the fuse fail immediately or after you drive for a distance? If you look at the pic below, note that power is only present in that fuse when the key is in the run or start position. If you turn the key on, does it fail right away? If it does, I need you to check the connector at the alternator. The green wire is the one of concern. Make sure it isn't damaged and the connector isn't melted causing the pins to short.
If that is good, then I need you to disconnect the battery and the connector at the alternator. We need to check if there is continuity to ground via that green wire.

If there is, we have a short in the wire which is the cause of the fuse problem. We will cross that bridge if we need to.
Let me know what you find or if you have questions. Don't feel uncomfortable asking. LOL Pretend I'm your big brother. LOL
Take care,
Joe
