Bike is dead after mistakenly connecting jumper cable backwards

I was jump starting my bike because I haven’t started it in a while and the battery didn’t have quite enough juice in it to get it going so I hooked the cables to my riding mower to jump it. But when I went to connect them to my bike I accidentally reversed them and there was a quick spark for a second and then after that the bike has had no life at all. I bought a new battery. No change. All fuses showed good continuity. My bike speakers turn on when I connect them to the batter so I know the new battery is good. But the bike shows absolutely no signs of life in any way. What’s the next step here? Thank you.

Check the battery voltage. Trace the wire from it and find if a fusible link has melted or a hidden main fuse has blown.
