I have a 97 King Quad I got second hand and just had the top end and carburetor rebuilt. It has ran flawlessly, as recently as this afternoon, but now the neutral light won't come on and it won't start. I'm sure there is a switch somewhere, but I can't find it, especially in the dark. I tried pulling in both of the brake levers and this did not override the neutral switch. I haven't bought a service manual yet so where do I look for this switch?

 

by the carb...look for a blue wire by itself.

My 97 Suzuki won't start unless this blue wire is connected. I disconnected it once while rebuilding the carb and had the same symptoms as you.

HTH,

Jason
