About a week ago I got on my ride and turned the key on and nothing happened. I bumped the dash and the display lit up and everything started working. Then yesterday i was riding the trail through the swamps when I stopped to put it into 4 wheel drive and it shut off. The display wont light up and nothing will work if it goes through the ingnition switch, the battery is still strong and the aux. lights I installed work. I checked all the fuses ad the ignition switch and could not find what was wrong, I realy need some help with this since the extended warranty just went out on it.
