Erratic ignition now no power, no start
 
My 2000 SV650S died last week. I cant work out what caused it! Any help would be much appreciated.
Battery has past its best but was fully charged and ok. Rode about 8 miles to meet everyone then went about 20 miles and stopped to regroup, all seemed fine.
When I fired the bike back up (10 minutes later) everything still seemed fine but when I pulled off I my indicator light was flashing, fuel light flashing and I think oil light on. Also rev and speedo needles were bouncing back on forth randomly.
I pulled over and stopped but it wouldn't start again! No ignition lights at all! It seemed like there was no power anywhere? No lights, horn or anything
A few roadside checks showed...
No power with different battery or jump leads
Ignition fuse ok (swapped with spare just incase)
starter fuse (30a) ok (swapped with spare)
Sparking from starter terminals, engine turned over and started twice but cut out shortly after. Engine turning but no start since.

After getting the bike home i found that there is power to the fuse box above the battery but I've not checked any other components as i'm not sure where to start. I did notice when stripping the bike though that the clutch switch has been bypassed. Maybe this has caused something?

Also, the only thing that I did different to normal is when I stopped I just cut the engine cut off switch and left it in gear. And when I started it left it in gear, clutch in and pressed the button. I'm not sure if the would have caused something to go wrong?

my first check would be the ignition connector.

Also check for corrosion in the Big Block connector under the tank at the front near the headstock.

Also pull and check all fuses and their slots for corrosion.

OK, so ive done a bit of probing with my multi-meter. As far as I can tell (and i'm no expert) there is power going to the fuse box, r+r and ignition switch but nothing going to the instrument cluster. No parking lights or horn, nothing. I tried this with a spare instrument cluster too and same result and so i'm pointing the blame at the ignition switch and on the look out for a new one.
Fingers crossed this gets me back on the road, ive just paid for new chain and sprockets last month!

you need to physically check the terminals inside the connector for the ignition switch for corrosion.

after that its the kill switch.

UPDATE!
OK, ive changed the ignition switch and still have the same problem.
How can I have zero power? No mileage, horn, nothing!
There does not appear to be any power at the ignition fuse.
Red wire on ignition switch connector shows either 6v or 1v
If the kill switch was faulty surely there would still be ignition lights at least?
I really don't know what to test first now or in what order

The wiring loom can chaff and fail, where it passes next to the tank hinge, worth a quick look.

Thanks, I’ll check that too.
I don’t think there is any power going to the fuse box at all? The starter terminals spark so I have power there.

The original symptoms ie. erratic ignition were what happened just before having zero power.
