Mechanic HELP !!! Fourtrax 350 2004

Hello everybody! I'm from Quebec, and I usually speak french... so it can be normal that I make some mistake in my text.

During a ride, my display screen stop to work... complete failure, same the orange back light didn't work.

Fortunately that the atv can runby himself because I was very far in the mountain...

So now I'm come back, but my screen is always broken.

A friend said to me that it was maybe my batterie. It has a lot of sense because when I tried to start the ATV the day of the expedition, the batterie was completely died. It's bizarre becaus the week-end before, the batterie was OK...

Well I finally buy à brand new batterie, but I didn't install, maybe on the next weekend.

After that, my friend said to me, that maybe that it's just à little fuse who burned.

So I buy somes new fuses (always usefull to keep for spare), and I hope that it will stop my problem... (I will check that on the next weekend to...)



So, what do you think about that, dear friends? I hope that it is not my screen board who is burned... or maybe the regulator??

Thanks for your help
