05 450 sportsman wont charge

[hunter101]

my wheeler was workin fine all winter, last weekend i went to start it and it was dead. i didnt leave anything on. i did use it in the rain fishing last week. now i can jump it to start it but it will only run awhile then quit. the battery is only a year old. but wont hold a charge, could it be the battery or do i have deeper problems?

Honestly, it is likely the battery. When I got my 02 Sportsman, the stock battey did the same thing after 18 months.

I troubleshot everything with a meter, and it was simply a battery that just had no capacity.

The rig wouls pull start and run just fine, but it would not start with the key.

Batteries need to kept on a maintainer or charged monthly to survive if not used. They will self destruct from non-use very quickly.
