Trx450fm help

Hey guys, Iím new to site and very mechanically green,

I am having a issue with atv, it ran about a month ago, I rode it for a day, Iím in Ontario so itís been cold, itís stored in a lean to, the next day it wouldnít start, I figured maybe too cold and I gave up, it did need a new battery, so I replaced battery. So now I have a fresh battery and last season I replaced ignition. Anyways when I turn the key the dash does not light, the headlight donít turn on. The winch works but itís wiring is directly connected to the battery, I checked the fuses by the battery and they are seemed fine. Like I said Iím not very mechanically inclined, I do want to learn and I had the online manual but somehow it got deleted and I canít find another one online, that would help. Iím wondering because Iíve watched some YouTube videos and seen one where there was another fuse block located under the frame different from the one near battery, Iím wondering if this is true with my model as well? Iím hoping that may be the issue.
If not what steps can you advise for me to try and diagnose the issue. Iíve cleaned the terminals and thereís proper connections, the electric start doesnít click or make any sounds when I push the start button.

Thanks for the time and patience

Try this link:

Sounds like either a blown fuse or a faulty connection in the main circuits.

Make sure the battery is not connected up backwards. Red on positive black on negative... you'd be surprised how many times folks can make that mistake.

NO dash lights

I did say I was mechanically green, but not that green lol,
I went back out and gave it another look, fresh battery, fuses appear good,
I did however notice my back light this atv has a middle back light I never noticed anyways one wire isnít connected appears to been broke off,the light appear so to only have one post To connect to, do both wires go on thatís post or not. And what something like that affect my dash not lighting?

I did download the manual, and Iím going to ask my dad To show me how to test the connections but heís not around for awhile so I was hop in maybe someone here has had the same issue and could offer some suggestions. Thanks
