Long story short I'm attempting to fix my father in laws 4 wheeler. It was shut off before it died. All you could see in the water was the seat and handle bars. Now I pulled the battery and hooked a battery charger directly up to the terminals of the 4 wheeler without a battery. the display doesnt turn on, nothing powers up. The key does not make the starter function. I then connected the positive wire to the junction box on the left side by the battery and the starter turned over. Is there a fuse somewhere that I'm not seeing? HELP!!!
