Okay, I just hooked the 4 wheeler up to my truck battery with cables, still wouldn't do anything but click. I am assuming it's not a battery issue. After unhooking the battery cables, I ran it through the gears while rocking back and forth, and it cranked right up. Cranked 6 consecutive times, then started clicking again. I also tried cranking it while in gear with brakes depressed as suggested, but got nothing.
