I took it off. There is a photo in the previous post of it. I'm guessing the previous owner connected it directly. New one doesn't look anything like that. Maybe it's blown maybe not, not sure. Ordered a new one. WIll see how it goes tomorrow. Hopefully, nothing burned.
Thank you so much for pointing at it. I thought it's 2 other fuses are the main ones.

If the last owner was blowing that fuse and just hardwired it, that is an enormous red flag.

Have you disconnected the negative cable from the terminal post yet. I saw plenty of suggestions, but I didn't see if the battery had been disconnected yet.

The reason I ask, is that I left my Jeep ignition on, and thought I had killed the battery. No lights, no horn. . . .nothing. As I was disconnecting the negative terminal, to replace the battery, it sparked. Put the terminal back on the post. Turned the key, and motor started. It was as if I had completed a restart on a computer. I stopped by the dealer, and asked if there was a safeguard feature to prevent complete battery drainage. The said no. . . . but, I don't have high confidence in this specific dealership.

I do know that some bike manufacturers offer a "battery management" system; BMW for one. They told me that if the system sees that voltage has dropped to a certain level, it shuts everything down to prevent further drain, so you can start the bike.

If you haven't disconnected the battery yet. . . . give it a try. . . . while you're waiting for the fuse. Good luck, regardless.

This is likely not your issue, but several times people have had similar issues because they made the mistake of installing a new battery upside down and connected everything backwards.
This will blow fuses and lead to issues like yours.
Please take a few minutes and make sure your battery is installed properly.

That's for sure. I hope thought he just blow it somewhere on the trip and hardwire it. Will see tomorrow. If it's not it I might have a pretty big project.

I removed the battery once. Oroginaly I thought I have a dead battery and replace it. Then I actually replace it one more time thinking I got a bad one. SO probably not it. But it might be some sort of protection mechanism. I'll research that.

You mean they connected the negative to positive? I don't think my cabels long enough to do it :) I checked all 3 cabelsI think they are for heated grips and additional charging port. Maybe I accidentally touch them, I'll find out tomorrow. I hope I did

I think the first step is to temporarily disconnect any non stock wiring, replace the 50A fuse and see if it will start or if the fuse pops.

Thanks to @alongrosman who pinted that I was wrong with the location of the main fuse my bike started! I also checked the cabels with multimeter that @Fordf350 mentioned. Everything looks fine. And I double check the ground as well. I'm going to remove additional cabels that not supposed to be there, heated grips and additional charger (I'm not using them anyway).
Will see if the fuse will blow again. I'll keep one more under the seat :)
Very glad nothing burned.

Thank you guys so much for your help. You all saved me lots of time and money. Very glad we are all here :)
