Has the ignition switch plug moved out of contact?---(common fault!)

Any signs of life anywhere?
Can I have a motorcycle when I get old enough?
If you take care of it.
What do you have to do?
Lot’s of things. You’ve been watching me.
Will you show me all of them?
Sure.
Is it hard?
Not if you have the right attitudes. It’s having the right attitudes that’s hard.

I have zero sings of life.I'm using a battery pack and I did check the key switch plug.All good.I do see a green wire that has no place to go. I don't have power to the top 2 fuses, just the bottom fuse.

If the loose green wire is under the left side cover by the electrics panel, it's a spare ground.  Some models use a 3-wire winker, one of which is that ground wire.

Its alive,Broken wire and blown fuse.However it blows a fuse when you hit the start, it started with a few kicks, yet one more cool thing about these old bikes.

Does it blow instantly or after a few seconds of cranking?

When you hit the starter button, it shuts off your headlight and causes a large round relay under the left side cover to kick on and send a boat load of amps to the starter motor.  I'd check first to see if the thick cable between the relay and the starter moroe has any nicks or pinches in it.  Repair with shrink wrap and/or liquid vinyl.

If no breaks are found, turn next to the wires connecting to the starter button.
