So last week i decided to was my 07 yfz 450, when i was all done i rode it down to my buddys house down the street. When i went to leave i turned on my headlights and went to start it and a fuse blew. Everytime i turned the key it would blow a fuse. Then i realized it only blew when the lights are on. So now as soon as i go to turn the lights on it blows a fuse and shuts iff. Ive looked thru all the wires and havent found anything wet or shorting out and i also looked at the lights and everything in there and nothings wet. Why is it doing this?

 

Sounds like a pretty closed case of a short circuit, just a matter of finding it. If the wires are all good, have you taken the switch apart yet?

 

I mean im pretty sure the wires are good. Im not an electrician so j dont know what to really look for besides a worn wire to where the actual wire is showing, and i didnt see any of that. And yes i took the switch apart and everything was fine and dry. Im pretty lost

 

It is blowing the fuse located back by the battery? I would start looking over the rest of the wiring harness then. While you are at it, put a little dielectric grease in all the connectors. Make sure to really check anywhere the wiring comes near the frame unprotected.

 

yeah its blowing the blue 15 fuse by the battery. Ill have to look thru it again its just a pain tearing all the plastics off lol
