Headlights and no ignition start up on my 99 Harley xl1200c

The soft click sounds like the starter relay. Check that out first and see that current is getting through when it soft clicks. ARE there any codes set??? What led up to this???

sounds like the fuel pump is going...have a dealer check it out

that is one grimlin that is pretty well cornered your ignition switch is command central for all you listed that was not working properly inside the barrel of your ignition are the contact pins that supplies power to everything that requires power that why when you turn ignition off everything shut down so your battery does not die out .i would say that there is a 99% chance that your ignition is shot.

check your ground. and pos connections....sounds like a bad ground to me
