Update on my 400 Rancher problem

My Honda rancher 400 2005 will now, along with the problem in my last post, not go into nuetral. Mechanically it will, but it won't register to the machine that it's in neutral and the safety feature keeps it from cranking. I can sometimes shake the quad around a bit and the nuetral light will flash, so I hold the crank button until the light flashes on and the quad will crank. When it's not showing N, it says -- in the box.


My previous post was called "2005 Rancher 400 Not Hitting High Gears"
this atv has given me nothing but problems since I bought it in 06

I'd appreciate any advice
