I'm quoting my answer to a different member's similar question:
The problem is at the ignition switch (key on/off). The way you describe which circuits work and which don't is perfectly consistent with how the ignition switch works. Look at the ignition switch continuity diagram in your service manual's wiring diagram. The switch has 2 battery terminals. When the switch is on, one battery terminal connects with IG1 and the fan, while the other one connects with IG2. Take note what is powered by IG1 and IG2:
IG1: Fuse B (top fuse) - Turn, Stop, Horn
Fuse D (5th from top) - Starter, Ignition
IG2: Fuse A (6th from top) - Acc. Term.
Fuse C (3rd from top) - Headlight
Fuse F (2nd from top) - Taillight, Meters
Looks like your IG2 terminal on the starter switch isn't getting power, so this could be either the switch itself, or one of the 2 red wires to the switch is broken. By the way, I'm just looking at my manual, not taking apart my switch to look at it. Also note the physical location of the fuses, top to bottom, is B,F,C,E,D,A, so I suspect your bike IS consistent with the diagrams schematically, if not physically.
The member's final message in the thread:
went out today and wiggled the key in the switch and guess what came on. everything worked and when i moved the key again all the lights went off. so i guess this is got to be the problem. thanks to everyone on this site you guys help the mechanical challenged more than you know.
