I have two quads, one is a 2003 warrior and i have not had a bit of trouble with it. But my 2001 does not want to start. The soleniod makes a clicking sounds like the battery has a low charge but i have had it load tested and even replaced when it still kept the clicking up. it starts fine when pull started. I have replaced the soleniod and am still having the same problem. i have been told the voltage regulator will cause this. Any ideas or anybody else heard the same thing?
