I'd suspect the problem has happened before but only the heat damaged wire
was pieced out, the real cause of the problem i.e. the relay was left behind
to damage the new wire. You need to do both, changing just the relay now
may result in a reoccurrence if the wire connector is heat damaged and makes
a bad connection to the new relay spade. Unless the motor or its wiring has
a partial short and is drawing too much current I doubt both were replaced
last time. And originally the fan was fused, so a partial short should have
revealed itself ... unless that has been bypassed because it did keep
blowing because of a partial short! You need to check that fuse as well,
indeed that it does have one, as that relay is not standard for a 4-cylinder
MGB cooling fan.
