Ok heres the thing, one day i went to get on my fourwheeler and it didnt start. It didnt even try to turn over. so im thinking that it is the cylinoid. So what do u all think?

 

Its almost always the battery.
The first thing to look at is the connections. They need to be clean and shiney(non oxidized), where they connect to the battery terminals. If that looks ok, then take the battery to any auto parts store...napa, autozone or whatevrer, and they will do a free load test on it. If they say the battery is good, repost.

 

Charge the battery then try.

 

I charged it and it didnt hold any charge. And i already bought a new batterie. from Walmart.
