Manual Fan Switch GL 1000

Post by moose4jesus »



The thermo fan switch is not working.
My Vetter fairing has an un-used toggle switch from some previous accessory. I'm very conscious of the temp gauge especially when idleing in heavy traffic. My question is what is the best way to wire the fan so I can control it manualy when the engine temp gets too high and is this a good solution?

I ran the hot wire to a toggle on the right side of the fairing.

Pull the plug from the fan switch and wire the toggle switch across the plug.

I see nothing wrong with a manual switch, but I don't see the point. Honda did a good job making it. I would keep the automatic switch and add a manual switch, if I wanted one. use a relay system though.

I would do the same thing, I would actually wire the toggle switch in parallel and replace the defective temp switch, that way the automatic system would still work but I have the option to overide it any time I want.. No relay required as honda already have a relay from the temp switch..

I was just looking at the wiring schematic and I can't find a relay for the fan from honda?

I have an 1800 and there is definitely a relay between the switch and the fan, it is very poor practice to drive a motor directly from a switch, so I assume Honda have a relay on all the wings for the fan, but that is an assumption and could well be wrong!! :oops:

I agree there should be one , but I have looked and looked at the schematic. I just can't see it.

Shoot, even the headlights on the early wings lacked a relay. The silly circuit had to run from the battery power, to the ignition switch, up one handle bar to the starter switch (to be killed during crank) then up the other handle bar to the high and low beam switch, then out to the head light. That was a huge reason for a relay, but only the blinkers and the starter got a relay. If you add relays to the headlight, the switch will last much longer and the lights will be about 15% brighter.

I did wire the toggle switch plug with a 22/18 gauge marine grade male end of a snap bullet connector- it fit perfect into the stock plug female end. I'm amazed how the 34 year old cooling fan still works like brand new.

Red color is the 22/18 gauge.

I had a bad temp sensor and wired a toggle switch across it, as mentioned above. My ankles would tell me when it was time to turn the fan on.
