got 2 brand new blue eagles 110 chinese atv's right out of the box niether will crank over or fire. when i turn key on the brake light comes, but when i press the starter button nothing happens, i can short solenoid and it will turn over but wont fire.

 

what's illuminating the brake light? is it receiving the signal from the brake switch or is it something else? if the brake switch is activated, that interlock is satisfied and should let the thing crank/turn over. curious if the light is crossed somehow illuminating the bulb or not. we've got to determine if the brake switch is working as it is one of the safety interlocks for the starting circuit.

 

check the kill switch on the left handlebar. the run/kill/run red button. make sure it is in the right position and not killing the quad. are you getting power to the quad other places with the key switch in the "on" position?
