OK, does anyone know at what temp the fan is supposed to come on at? I don't think I have ever seen of heard it come on. Yesterday it was 97 here and riding home it was a little hot, to say the least. At each stop, I looked down and it wasn't on. Any ideas/suggestions?
Fan on my 05 800 almost never comes on. Have quite a few high 90 low 100 days here to. May be ok, but to be safe, should get checked. Even 2 hrs shop fee cheaper than. Ew motor!
First, remove the left side cover and open the fuse box. Locate the fuse for the cooling fan and check that it's OK. Next do what the dealer will do with it. Finish your ride and park the bike with the engine running. If the high temperature light comes on before the fan then you know there's a problem.
I guess my advice wasn't THAT bad......lol.
It's how I check MY fan....you can't "bake" the engine....sheesh, there are lots of air cooled engines around.......
However, trouble-shooting the fan is prolly a better idea....
Take it for a ride.....stop at a location and have a smoke,,,,,and let it idle for ten minutes. If the fan doesn't come on it's not working. My fan RARELY comes on.....if at all! But, it will when i let it idle on HOT day. We do have a temp light on our bikes.....is it ever on?..sheesh, i think we do....fi, oil and temp?
before you try to overheat your bike. check the fuse, then the fan is very simple two wire setup. grab some old speaker wire or any wire you have really and run voltage(from battery) directly to the fan. It should spin. if it does you know that it good and you can go on to check your temp sensor and other connections. I dislike the idea of prolonged idling with not knowing the condition of the fan. It is hard on the engine and if it really isn't working you may cause damage even if shut down when the light comes on as you aren't circulating any coolant at that point it will sit and bake when shut down.

I had the same problem a few years ago. Bought a fan motors for her off ebay, installed it two years back just because I was paranoid. Turned out I had a good reason to be, the new fan comes on all the time when it hits the mid 80's to 90's here. When she is running the temp is fine, but at idle that fan should kick on fairly quick in that temperature range.
OK, I have an '05 800B. To check my fan, I read someplace, to just pull the connections off the raditor temp switch / jumper them, and the fan should run. I've done it and it works on mine. This doesn't test the temp switch itself, but it does verify the balance of the system.
With the Vulcan the temperature sensor feeds into the ECU then out to the fan motor relay when additional cooling is required. Not sure if your method would work.
My fan died last fall. I tested it using the wires to the battery method. Picked one up on ebay. Pretty easy job if you are somewhat mechanically inclined. My undying thanks to Sojourner for all his help during my hour of need! Heres a link to my thread on this. This should help you out with most any questions you can think of.
Thanks everyone for all your input. Its an 2011, so its under warranty for a while yet. I'll check the fuse today and test the fan as well. If its bad, I'll take it in and let them deal with it.
The plug end is under the tank on the backbone with other plugs. You would need to remove the tank to test it directly off of the battery. Easy enough to remove the tank. You can be sure the dealer will use the easiest way to test the fan. I've already posted what they will do.
Is it possible to use vulcan 800 fan system on a 900..my vn900 fan chip quite a few blades...kawa don't sell fan only..need to buy whole fan system..and that cost a lot..I just need the fan..did anyone know where can I buy fan only..motor still working..just fan..
