My father have a 1994 kodiak 350, which was starting fine up until yesterday.
While hunting, we stop for a little break, then when he went to start his ATV, there was nothing, he had to manually start it.

His first guess was that the battery was dead, so he bought a new one, and same think.
He discover that on the side of the battery there’s a round piece with some wire, and that’s where the clicking noise is coming from when he press on the start button.
Is there anything to do to solve the problem, or if that piece is completly dead ?

I want to try to help him save 50-100$ if he can just solve the problem by himself instead of buying a new piece
