you find the two switches then you can beat LT.Surge PS:check the garbage cans in the gym.
Check the trash bins. they're two switches to open it. once you find one switch, if the next one isn't the other switch, it all resets.
The third gym is in vermillion city. The Gym Leader is Sarge, and he uses electric-type Pokemon.
You can use a cheat to walk through walls
Assuming the 9th badge is the Vermilion City badge (the only gym with an electric fence), you have to randomly find the first trash can switch. An adjacent trash can will have the second switch, but you have to guess. There is no way to find out about the second trash can.
* Pewter Gym - Rock Badge * Cerulean Gym - Cascade Badge * Vermillion Gym - Thunder Badge * Celadon Gym - Rainbow Badge * Fuchsia Gym - Soul Badge * Saffron Gym - Marsh Badge * Cinnabar Gym - Volcano Badge * Viridian Gym - Earth Badge
If you mean Vermillion City, The switches to turn them off are in the Garbage cans

check trash cans for hidden switches

There is no easy solution to the electric fence puzzle in the Vermilion Gym, all you have to remember is that when you find the first 1, the next one will be directly next to it but it could be either the northern one, the southern one, the one on the left or even the one on the right, the switches are completely random for every player.
The 9th Gym would be Vermillion. It's the standard Vermillion Gym puzzle, search through the bins till you get a switch, the second one will be next to it. (Up, Left, Right or Down) - The Gym Trainers will take you this when you defeat them. It might take a few attempts, but it's not difficult.
Lt. Surge in Vermillion. He is an electric type trainer, just to let you know.
They are in the garbage cans
After beating cerulean cities gym head down from cerulean and enter the underground path go through then go down and there is vermillion.
Vermillion City (kanto)-Lt. Surge Electric Type- mid 40s to low 50s. Ground Type Pokemon great against this gym.
you look through the trash cans and try to find both keys. (the keys are usually two away from one another!) ;)

You will arrive in Vermillion city after from Olivine. Lt. Surge, the electric gym leader, is here.
