Need help, grizzly won’t start

Tried searching and came up with a few things but still can’t figure it out.
Here’s the way things are going:
1. 2009 550 eps Grizzly wouldn’t start, 12 was displayed in the lower left hand of the display. Loud clicking heard. Did some searching here and it said maybe battery. Called the yamaha shop near by he said confirmed and said start with a new battery (original one was still in)
2. New battery in, go to start and it’s still making the loud clicking. Except now the display doesn’t display 12 anymore. As I’m hitting the starter it’ll display either er_1 or just a 64.

Thoughts? I’d rather not take it to a dealer….
