Gotta say, as an old Harley guy, fuses and grounds are my thing. I have tested them with no luck so far. Yet, I agree with you, it seems like a very basic problem. Now that I have a wiring diagram, I plan on checking positive and negative wires to the handlebar on/ off switch to the plug at the front frame connector. So, off with the tank and that PITA rubber cover to get to the wiring harness. Thanks along with others to give me confidence that I didn’t plug anything back incorrectly at the front harness.

Since the speedo tries to do its' startup sweep it implies that things are connected correctly, but you aren't getting enough voltage. You could pull the battery and get it load tested. Also, that's a lot of charge to lose overnight with no fuse in place so it might be toast, which the load test will tell for sure. And, it gives you a chance to clean and check the connections yet again.
If the battery passes muster you might have one or more connections just 'barely' made. You could redo each connection using a bit of lube to ensure the rubber parts aren't holding things back. I haven't had this happen on my bike, but definitely on other applications. I'm sure you'll get it sorted if you were able to keep your old bike on the road all those years!

Thanks for the encouragement. I’ve got to admit, I am a bit intimidated by this whole CAN Buss system. Tomorrow, I tear out the rubber frame seal and re-plug the connectors checking for loose pins or wires or just not plugged in enough. If nothing shakes out, a load test on my battery at my local Napa store is next. Not sure why I am waiting to replace the battery, but I am a cheapskate at heart. Certainly it is getting old especially in these hot temperature days.
Thanks again. Of course I finally ended up putting in a manual stick solenoid replacement in my shovelhead, not to mention an accompanied Ford solenoid after a few stock solenoid rebuild kits.
