Sometimes fuses can do that after prolonged exposure to motion/vibration. That's one of the reasons aircraft have circuit breakers instead of fuses. I'd say don't worry about it. Now, if the fuse blows again, I'd say you might have a problem. Time to break out the wiring diagram and the ammeter and start looking around...
