I put my sons quad away the other day and left the key on. Next day it wouldn't start. I tried charging the battery, eventually put a new battery in it. Still all I got was a clicking in one of the relays. A friend tried jumping one of the wires and now i don't even get a click. Does anyone have a clue what it could be?

 

Is there a reset button under the right rear fender?

 

Try checking the fuse???

 

this happened to my sons 87 lt80 ,it was the starter ,try taping it with a wrench or something see it it will catch. if you here clicking your relay is good.since it stopped clickig your starter fuse may have blown trying to jump it. i bought a starter on ebay for $60. works great. good luck
