I bought a eton viper 90 for my son and it has a tetherkill switch on it becauseit was used for racing.. I have replaced plug and ignition coil on this quad and has no spark.. Any thoughts?

 

Ohm the stator...should be something somewhere on what is acceptable...or test voltage from stator to ensure juice is being produced.


And ensure that any kill/stop switches are "on"...maybe bypass tether if questionable...

 

I'd ohm the tether wires to make sure it's working.
