I have a 2013 sportsman 500 ho with 700 miles on it and the fan kicks off and on. I changed the radiator fan switch and the coolant sensor. It didn't solve my problem. I have checked all fuses and couldn't find any breaks in the wiring. Thanks for any help.

 

Its suppose to kick on and off.

Get nervous the day it never kicks on or never shuts off.

 

I know it is but mine is kicking off and on very fast. It won't run through a complete cycle of cooling down and then heating up. It kicks on and off so fast that it over heats. It runs continuously on and off on and off. I jump it straight from the battery and it runs like that. Thank you for trying to help.

 

Start at the fuse panel and check for any shorts in the fuse block. Leading from the fuse panel, is the fan relay that is usually powered by a 10 amp circuit breaker located further up the harness either taped to the harness or in a sealed pouch. Possible the circuit breaker is corroded and tripping not allowing constant power to the fan relay and fuse block. Shows the 10 amp breaker on the parts list along with a couple other breakers.Dirt Cheap Yamaha, Polaris, Suzuki & Kawasaki OEM Parts & Accessories – Cycle Parts Warehouse If it runs intermittently by straight jumping to it from the battery also,then could be the fan motor itself is faulty.
