Won't turn over
 

Bought my daugther a gio hummer 110. 20 minutes after she turned it off, only the soleniod clicks. I charged the battery, same thing. I tried to boost it, same thing. I went out a bought a new startor, same thing. I tried to arc the soleniod and the startor humes. Any ideas

If you take the starter out and leave it hooked up (ground the starter frame to the quad frame) does it turn when you do the normal start sequence (ignition on, brake set [with brake light on], and start button pushed)?

Take off the side covers and see if the engine will turn with a wrench.

Take out the spark plug and repeat the engine turning test.
