My 900 shut off on me, and now wont turn on at all no lights no nothing.

 

Check stator and battery good luck!

 

The battery is good, I didnt check the stator

 

make sure you have a good ground

 

Is it possible that it could be the computer?

 

Could be the ignition switch or main fuse if there are no lights at all.

 

what computer
check grounds and battery possibly fuse problem

 

What computer??
Check the battery connector too. It might appear ok but sometimes the contact surface might be rusty. Try to sand paper it and install again firmly. I had this problem once and been rectified by the said way.

Good luck.
