Electrical system died...

Spring start-up. Charged battery, cleaned and greased connections. Ignition on, all idiot lights worked.
Touched starter button. There was a small "snick" sound and all was dead.
Battery still at 12.5v. Checked all the fuses, main and those in the fuse box. All good.
The bike was running fine at the time it was winterized and stored. There is comfort in that
but much dread on account of the snick sound.
Key, kill switch, stand in proper positions and bike in neutral.
Where do I start looking and testing? I have a multi-meter and a good selection of tools.
Need a few clues if you would be so kind.

Simplest is to open up starter button and kill switch and remove any corrosion. After that, since you checked all the fuses, battery connections etc etc you need to test starter. But you say all is dead so recheck fuses.

I should have been more clear, apologies.
When I said all was dead I was referring to all things electrical,
Horn, signals, lights and all the indicator lights.
It is as if I turned the ignition key off.

Check for corrosion along the battery cables, terminals and connections.

I am coming from an older Triumph Tiger background.

My bike did that once. My testing pointed towards a defective ignition switch. I was ready to replace it. Before I replaced the ignition switch I disconnected the battery, I filled the keyhole with WD40, sprayed all around the key assembly with WD40. I worked the key on and off many times to allow it to scrub against the contacts. I let it set overnight, reconnected my battery and it worked and I have had no more issues. It is simple and cheap. I hope it works for you.

One other thing is disconnect your battery and jump straight from a vehicle, make sure it is off. Make sure your motorcycle battery is good. I have had batteries short out, show volts but have low amps etc.

Yeah, a battery may read 12.5 volts without a load. It gets loaded and the voltage drops when you try to crank it. My battery would light all lights etc but when I tried to start - no go - and noticeable dimming of all lights. Swapped it n voila.

There is power in the cables down stream from the battery, at least enough for the indicator lights
but the power does not reach them.
The snap sound was electrical.
I'll do some 007 investigating tomorrow and double check everything.

I don't have the same setup but if yours has the start solenoid with the main fuse plugged in, I remember other guys with a burnt terminal in red connector to that unit. That feeds the ignition. See if you can take the connector off and if there is a black or melted terminal.
