I assume you're talking about the radiator fan. Start the bike and let it run; when the bike reaches a high enough temp, the fan will kick on (manual will state the exact temp, but your guage does not show numbers, only a range).Hello community,
What is the procedure to test if my radiator comes online when it should?
How could I add a switch to get it running at will?
Thank you in advance
Usually the high 1/4 of the guage is were mine kicks on.
I would not bypass that for a manual switch; human error elements usually lead to catastrophe. Your fan will either turn on as advertised, or it wont and you'll need a replacement. Check your fuses first and ensure the fan fuse is not popped.
