Due to my fan not work properly due to a faulty fan switch I made this modicification on my 86 Vulcan.

Basically flick it on to operate the fan when it starts getting hot.

Normally this would happen automatically, but untill my new part comes in, this keeps me on the road. Not my idea, but I did make it. Just a $2 toggle switch connected to the fan lead, the other to ground.

It works.

I love this switch. Just turn it on when the traffic gets heavy or sitting at the lights.

Hey Denny, would there be any reason why I could not keep this switch permantly, but also still have it connected to the Fan switch as well ? Ie with a two way wire on the Fan wire,

It would mean some addtgional insurance for me, as the bike runs hot in traffic.

If this is working for your purposes, I would not see why you could not keep this setup but I would only ask why you would want to have the manual control of the fan operation over the automatic stock setup. The reason for my question is only for my own personal clarification and understanding. I am just wondering if I may be missing something that could be a real advantage. I would not trust myself to flip the switch on and off when needed. I know when I ride with a group and we come to a stop in traffic (traffic lights, heavy congestion, etc.) I am usually trying to to position myself to talk to someone in the group regarding directions or such and would probably forget to turn the fan on. I am also the one that most often forgets to turn off my directional signals after making a turn. I am all in favor of going with what works for you as an individual but also I want to know if there is an option available that I may be over looking and can help me ride more comfortably and help my ride be more efficient.

I dont forget to turn off my blinkers as I have an 86. All automatic. That gives me enough time to think about temperatures. My bike runs hot and Australia is generally hot. The UFO switch lets me regulate the temperature by operating the fan before the Automatic sensor turns it on. It was great in traffic today, as it never got hotter than half way. Before (yesterday) I was running into the red, but I will wait and see how it goes when my new fan switch arrives.

Maybe its not needed at all, but I will leave the UFO switch on until I am satisfied that the fan comes on early enough and long enough to cool the bike. It just gives me comfort that I am not going to overheat, as I can turn the fan on as soon as the traffic slows and not wait until the sensor kicks it in.

I did a test with the bike at idle and nice and hot. Temp guauge was just passed the middle. I put the fan on using the UFO switch and the temprature guauge just stabilsed. Itd id not go down when the bike as at idle with the fan on. I turned off the fan and let the bike get hotter until the guauge was 3/4 hot. I then turned on the fan and it just stabilsed the temp, not hotter or cooler. Maybe its just my bike, but I figure the sooner I can have the fan on the quicker the temp stabilses in traffic. Its not needed at hwy speeds as the bike runs at about 1/2 without the fan.

You can leave it in if you want and run it paralleled to the automatic sensor switch,and have it both ways if ,you want to keep it.The fan will function normally even if you forget to flip the switch.

Just run a wire from the side of the switch that you put the factory wire on ,to the terminal on the sensor,or tie into that wire down closer to the radiator and hook it in to the sensor,Beat of both worlds and you can have it work when it feels it needs to or when you think it needs it.It will then be automatic with a manual override switch. :smiley_th

I was reading elsewhere that a lot of the earlier GPZ900's has a manual fan override for precaution. They ran hot as well.

Thanks for your help.

Mine has the fan disconnected from the PO. As I'm still learning to ride I only go short distances so it hasn't been a problem so far. Any time the fan is reconnected it runs non stop. I can hear a buzzing in the junction box so I'm thinking it's a stuck relay. Already tried beating on it (love taps). I thought about wiring it into the low beam headlight power but that would run the fan more than needed. I may just wire in a new relay if I can figure out how.
