Hi Yall

I need some help ! Took my Bombardier DS650 out for a ride yesterday and went through a large'ish puddle of water. About 50 meters later I started getting firing issues en then the bike just died on me. Tried to start it again and just heard a clicking sound bit it wouldn't fire up. This morning when I tried it again its completely dead . No power , not even the ignition lights are comming on.
Could this be a dead battery ( charged it over night)

Any help or advice would be greatly appreciated!
