When I turn the key, nothing even turns on. No lights, no option to prep the bike.

I just pulled the battery fresh off the battery tender, installed it.

What could it be? Fuses? Relay? I'm not ruling out that the battery is failing.

Do you have a jump pack or a way of jumping the bike.

9- times out of 10 it is a battery issue
8 times out of 10 it is a connection to the battery issue
7 times out of 10 bad ground.
Verify the ground wires are tight.
In most cases there are 2. One to the starter, and another to the Case below the airfilter.
6 times out of 10 Kill switch
flick your kill switch multiple times, can even spray with contact cleaner. They are prone to corrosion on a bike that sits outside.
5 times out of 10 Start button. Do the same as above to the start button
4 times out of 10 it is a Brake sensor.
Check your brake light turns on when you pull the brake
Try both front and rear brake to start the bike
3 times out of 10 Antenna for the ECU does not recognize the key.
You will need to check the red LED on the speedo. you can search for what the blinking means.
2 times out of 10 your ECU has failed.
1 time out of 10 Your key has failed.

Good luck I was trying to be funny and helpful at the same time. These are all the troubleshooting steps I would take and in the order I would take them.

I had a similar problem with my GT200. But a GTS will likely be very different because it has EFI. On mine the headlight came on, bit nothing else. A jumpstart pack didn't help. The battery tested good, the kill switch tested good, the problem eventually turned out to be a broken wire inside the insulation on the wire that goes from the kill switch to the CDI, with NO damage to the insulation. I hope you don't have something like that.

Side stand folded in?
Kill-switch? (Switch back and forth several times to eliminate any corrosion)

Please explain what do you mean with "nothing even turns on. No lights, no option to prep the bike". Does "nothing" really means nothing?

Then check main fuses in battery compartment (Do not only check visually, better measure for continuity!)

Do you hear fuel pump when turning key to on?

Put a volt meter across the battery see what its pulling, If its showing a good 12 then try a drop test if it goes down check earth cable for poor or corroded or frayed connections.

not just the fuses in the glovebox. also check the fuse that's on it's own near battery (30amp iirc). there's another one else where too - check the manual for locations.

use a multimeter to check them - not your eyes

update: the battery was toast. swapped out a freshly charged PX battery from a diff bike and it started right up. ordered a new YUASA YTX14-BS and have had no issues.

thanks for the help squad.
