I have recently purchased my wife a 2005 Trialboss 330 and she has riden it twice. 1st ride rode about three hours and her fan ran constantly and the temp light came on. Contacted the Dealer and he replaced the ECM module. 2nd ride out and the same think happened and suggestions on what the problem may be or is it another bad ECM? Any thoughts would be appreciated.

 

On my 04 trailboss the fan only comes on on 85+ degree days, and then only at at low speeds or when idling. I have never seen my temp light come on even when riding on 90+degree days. Take it back to the dealer!

 

I have a 330 Mag and mine did the same thing last winter, turned out it was the CDI box being bad and blowing the temp sensor. Dealer replaced both and no problems since. I think there is or was a recall for it, might want to check it out

 

my trail boss 330 fan would only come on if i rode it at low speeds on a 120+ plus degree days.
