Hi John and welcome to JustAnswer,

Thank you for the question and your patience. Should you still need assistance for information purposes only...

Initially, it would appear that the Polaris is electrically/completely dead. Proposed preliminary tries (if have not been done):

  • • check the fusible link from the starting solenoid's battery + terminal;
  • • check fuse block and reset circuit breakers.
