660 Grizzly is dead and won't start help
 

A couple of weeks ago the Griz was running fine. went to use it the other day and it was dead. I assumed a dad battery. charged the battery and nothering. tried jumper cables and nothing, put a brand new3 battery in it and nothing. The screen light nothing comes on. I see some fuses / links under the seat but the owners manual does not have anything on them. It is like a master fuses is blown. Any help would be appreciated

Get a volt meter and start chashing wires down. Look for good grounds and good clean connections on both ends. They do have a main fuse so check for voltage on each side of the fuse.
