Hello,my 2007 500x2 efi,wont start,when turning key to start,nothing happens,if you giggle the wires,any wire anywhere,sometime the lights gauges and sensors will come on for a second then go back out,sometimes lights come on and starter only clicks.i had battery tested at advance auto,they said it passed at 12.49 volts,my repair manual states the battery must be at 12.8v,any ideas,(battery)?please help.

 

sounds like a bad ground or a broken wire somewhere in the harness to me. I would start by checking ALL of your connectors and grounds from stem to stern, making sure they are all clean and tight.
