I have a 2000 Artic Cat 500. When it wants to run it does and when it don't it won't. When the neural light won't come on it will not do anything. I can ride it in the woods to hunt and it is running good, come back and the light won't come on so it doesn't crank. I can wait maybe try again and then it will come on and crank or I have to push it up on the tailor and maybe when I get home it will crank again. It is very undependable. It won't stop running long enough to get someone to find the problem. Any help will be appreciated.

 

I have a 400 same year same electrical set up. One of the issues I encountered with that bike is the Electric Start Relay. Since all the power to the bike passes through it if it has issues you got nothing. I replaced mine with a universal aftermarket off ebay for 10$ and solved the problem. Possible the neutral start relay is going out as well or worn wiring in there somewhere.

 

Well those are two good places to start. I will give it a try and thank you very much for your time.

 

If you need a wiring diagram you can pull it from here. Index of /pdf/Arctic-Cat-ATV-Repair-and-Service-Manuals Its 500 megs but you get all cats and snow cats 2000-2009.

 

Thanks for the wiring diagram. I was looking all over for this. I think maybe now I can find my trouble. So again a big thanks to you.

 

Great share.Thanks!
