Electronics are dead
2004 Sportster Custom. Riding down the highway, after ~ 50 miles speedometer goes to zero, digital trip meter starts blinking, engine running but very poorly. Limped to a place to pull off, engine still running. Shut off via the ignition switch and got off to do a visual inspection, nothing unusual. Turned the ignition back on, everything is dead.
Hauled it home and started checking things out. Battery and battery cables good. Exposed a place on the battery-to-ignition switch wire and the ignition-ON wire. Current to ignition switch is good.
Discovered 2 things that are odd.
1) Ignition-ON lead coming out of the switch is hot regardless of ignition state. Confirmed by checking the fuse box. That indicates to me that the ignition switch is bad, correct ?
2) When I connect the engine casing and the negative battery terminal (via a multi-tester) I get current flow, regardless of ignition state. That doesn't seem right to me.
1st time working on HD electronics so maybe I'm really missing something. Any guidance would be greatly appreciated.

Something very similar happened to my 04 Roadster after touring in the rain for a day . In my case it was a few water droplets inside the eight pin connector under the tank . I suggest that you pop all the connectors and look for any signs of sizzling or traces of moisture .

Thanks.
Got the wiring diagrams.
Can't get any diagnostics, The speedometer, lights, etc are dead. Maybe if I had the HD scanning tool.
I still don't understand how there is power to the fuses without the ignition On. Proceeding on the assumption that I have a wire shorted for now.

Maybe it's something I should look into then . Does it have to be connected to a device ?
