We can use the schematic to understand how the circutis work and what to expect.
For example. What wires and circuits are hot with the key off?
What happens if we open the door and step on the brake pedal leaving the door open?
And here's how the circuits work with the engine running
and the battery recharging.

Knowing what the ammeter indicated before the fuse blew would help us figure out what is causing the line to have more than 30 amps go through it.
