My 750 Vulcan radiator fan starting running constantly even after the bike has cooled off. The only way to get it to stop running is unplugging it. Can anyone give me any information as to what might be wrong. I am thinking the thermostat may be the problem but don't want to send it to a shop if I can help it. Would appreciate any help.

 

I would also agree on checking the T-stats condition. Maybe tapping it to unstick may help, but be prepared to replace the stat as an option since it seems to be sticking. Good luck and welcome to KF
