Hey, new to the forum! I just purchased a 2004 sportsman 400 and it seems to have an issue starting. it seems to do fine for the most part, but if the fan is running, it will just click when I turn the key. it will also do it out of the blue sometimes. Is this just a case of the battery not being strong enough to start it? or is there a bigger issue? it has a bunch of accessory lights aswell. Thanks!
