I guess hanging loose like the pic the terminal may have shorted to the body with the ign sw turned on or acc thus overheating that wire but if that is the case all the current would have also flowed thru the sw and done damage there. That wire just energizes the coil windings to pull in the relay contact. The coil is a higher restance and draws fairly low current and due to the design they usually fail open. I have never seen that coil fail shorted. It would have to have some foreign metal inside the relay cover. I think if there was a short and enough current was flowing long enough to burn that wire the ign sw contacts and assoc wiring may well be damage.
