May 13, 201313 yr At what temperature or how long idleing is the normal for the fan to kick on, on a 12 290? I removed the map switch tonight, and had to disconnect the grounds at the top of the frame. I connected everything back and just wanted to make sure everything was still working, but the fan did not kick on. I only ran it about 5 minutes, sitting on a stand, it was pretty late and i didnt want the neighbors complaining, but the fan didnt kick on. Maybe just not hot enough? i did put 12v to the fan and it ran fine.
