Hey guys. New to the forum. Very informative although I haven’t found my answer just yet. My 3 year old quad was intermittently starting and " horning" when the key was on….now it’s totally dead, although good battery. Tried starter (works) (hot wired horn and it works) very weird. Seems like the key ignition isn’t working or something else. I’ve cleaned all contractors, put new starter relay…..cdi works too. There’s a little black box on the left front with 2 connectors going into it. One 4 wires. One 2. Could that box be fried? Seems odd that the horn doesn’t even work…..any ideas?
