polaris 50 won't start
 

my friend has a polaris 50 and it will not. Can hear the relay clicking,fuse looks good, and has a new spark plug. Is there a circuit breaker on this quad like the LT80 that was having the same no start problem? Any info world be helpful.

First things first; does it turn over when you push the start button? Is there gas in the tank, with the petcock in the ON position? Have you checked compression? You want 120+ PSI.

Report back after checking these thins or if you have more questions.

have you checked the battery's voltage? have you had it load tested? if the battery is deficient in voltage, then it won't be strong enough to activate anything. the solenoid will just click. have you jumped the solenoid posts? if applicable, are all safety interlocks satisfied to start it?
