To beat Surge, the Electric type Gym Leader is use Ground Pokemon. Happily Electric type moves does not affect Ground type Pokemon. Also Electric type moves are weak against Electric, Grass and Dragon type Pokemon. However do not use Electric, Flying or Steel Pokemon moves as they are not very effective. Please DO NOT use Water and Flying Pokemon because Electric moves are super effective against your Pokemon. Use Pokemon around Lv 22 and higher for victory! Hope that helped!

The third gym leader is in Hearthome City. But i think the gym leader says that you are not ready yet. (don't remember) you have to beat Pastoria and Veilstone's Gym leader first and then you can battle Hearthome's leader.

After beating the third Gym Leader (Maylene the Veilstone Gym Leader) in Pokémon Diamond, you then head to Pastoria City to battle the Gym Leader there who is named Crasher Wake.
