@jobiwankenobi: Though electricity is one of the main things that harms like, it depends on what he has with him. In other words, he DOES have helpful items. I'll say it again, The Mirror shield would deflect any electricity.
If it's the OOT version we're talking about, Link would have the mirror shield. The Mirror Shield can deflect things such as magic, fire, Ice, and electricity.
He does have the mirror deflects it, so any projectiles he throws could get reflected back.
I'm not sure where you all are getting this. The Mirror Shield never reflected anything besides sunlight and the projectile attacks that were dealt by the bosses of the Spirit Temple. It's not deflecting electricity. It couldn't even deflect Ganondorf's magic attacks at the end of the game (I tried it before, and that was the closest thing to electricity, the difference being that it was magic).
