This is pretty good, but i have a few suggestions (i will rate team members individually).
1- Give someone the air balloon it is good for switching in and avoiding super effective spikes and earthquake.
2 Use rotom for coverage as all of it's forms are part electric and they all have levitate meaning it's like they aren't even electric.
Now team ratings
Ampharos: Good, lots of coverage, but if it's a lead use taunt to stop spikes because your team has weakness to them. Consider switching out thunderbolt for volt switch(i know it sounds dumb but i think your team needs to have more technicality and this could bring out air balloon manetric)
Manectric: He is fin, but he should have the air balloon so he can switch in on an earthquake for Ampharos.
Luxray: Take out Take down for Crunch.
Zebstrika: This thing is okay but should not be in your team unless you want to waste a party slot. If you love sap sipper than use leaf storm rotom. if you don't care for sap sipper run wash rotom

here are 3 GOOD substitutes for zebstrika
rotom: the only electric type that's immune to ground attacks and STAB supereffective hit them
electrivire: OMG how could you forget this guy/gal? one of the best electric types.
galvantula: can use agility electro web and electro ball to OHKO most people and ground is only neutral to him/her
Rotom wash @ choice scarf nature quiet role:coverage/revenge killer
moves
Trick:to lock opponents into 1 move
Thunder:for rain
Hydro pump:STAB use in rain
HP ice:for grass or ground types
use this for killing ground types in rain once you've trapped them into a ground attack with your choice scarf. but if you want it to set up rain switch out hp ice for rain dance.
Rotom frost @ choice scarf nature quiet role:coverage/revenge killer
moves
Trick:to lock opponents into 1 move
thunderbolt: safer than thunder
blizzard:STAB use in hail
hail:for blizzard
this moveset focuses more on killing ground types with ice instead of water.
electrivire @ leftovers(if you use wild charge)or electric gem (if you don't pick wild charge) nature:adamant role: physical sweeper
moves
thunder punch/volt switch/wild charge: STAB
brick break: break screens
earthquake: COVERAGE
screech: lower defense (you can use this then volt switch for elecktross)
pretty straight forward but consider screech and volt switch with the electric gem it's a pretty nice combo.
galvantula @ magnet nature: timid role: uhh i guess a sweeper i don't really know ability:unerve
moves
electro ball: STAB with insanely high speed
agility: for electro ball
bug buzz: STAB
light screen: should keep you alive until your have max speed.
galvantula @ magnet nature: modest role:a special sweeper ability:if your not running rain compound eyes
moves
thunder: STAB good accuracy with compoundeyes
energy ball: to kill rock types
bug buzz: STAB
(last move has to many good choices so your pick)
self explanatory
Elektross: Get rid of hp water for coil it'll help you sweep.(coil is learned in as elektrik)
Mangnezone: Try quiet nature gyro ball and see if you like it if not all's good.
NOTE I WILL SPECIFY ABILITIES ONLY IF THAT POKEMON HAS A CHOICE OF THEM
