Hello everyone, I have a 2003 and was riding Sunday and got back home just about dusk dark and notice that my headlights were not working (hi or low beam), I know there were working 15 minutes prior to getting home. I have checked the fuses and they are good. I am not getting power to the hi or lo relays under the seat. I ran a temp. wire from the + side of battery to coil on relay and they come on. Looking at the wiring diagram, the only thing between the fuse and the relay coil is a diode and I find it very hard to believe that the diode (if I could find it) is bad. My book shows a picture (not a very good one) of where it's suppose to be but I have yet to find it. Anyone else ever had this problem? A diode is only something to direct the flow of power in 1 direction only such as a check valve would do in other applications.
