300ex wont start

I dunno what else could be wrong. wiring harness is all new. starter servo is new as is the battery and fuses etc. Its gettin power since the lights can be turned on and off. And you can jump the starter servo with a screw driver and the motor turns over. But if you use the start button there is nothing. I dont get it. What could be wrong????

On the 300's some people have trouble with the start buttons. I know I did. Try taking the black box apart and finding the 2 wires that start it, and touch them together. If thats the problem then replace it with a dirtbike killswitch, and you shouldn't have that problem again.

even if its brand new out of the box???? I highly doubt that. What about if you dont have the lil clutch switch hooked up? Does that have anything to do with it.

is there a little click noise when you press the button or nothing?

Mine is doing the same thing right now. I can jump mine with a screw driver and it will turn over. Only thing different is my nuetrel light wont come on.

i dont have those lights jsut headlight and tail light. I dunno if the quad is in nuetral or not. I know that 250x's can get stuck in reverse. Can the 300ex get stuck in reverse as well?

another thing that might be the problem is i dont have the wiring for the reverse on the right side of the case. Im thinking now that might be why it wont start. The quad doesnt now if its in reverse or not.
