fan switch

Postby tprender » Thu May 05, 2011 9:23 pm



I have an '81 wing that I got just over a month ago and this week the fan stopped coming on. After checking it out the other night, I came up with the conculsion that the fan switch was bad. When looking on the internet for one, it looks there is mine (2 prongs)has been updated to a single prong model for half the cost. My question, I guess that I have to change the wires, but how. I did find the 2 prong model for about $80 and the single prong for about $40. I did fix it for right now by putting is a toggle switch, and me turing on the fan by hand. why so much for the double model campared to the single model?

You are more than likely seeing the fan switch from Saber Cycle, yes the 37750-611-154 MB9- 000 # is the correct one you need..Good luck with your fan switch whoever you get it from..

The wiring of the bike is this.Power goes to the fan,1 wire goes from the fan to the switch(it will have volts on it with the key on),when that wire is shorted to ground the fan comes on.The second wire on the plug is the ground wire.Using a single post fan switch,the ground wire is not used,as the single post switch grounds to the metal jacket rather than to the 2nd post on the original.

So from what you are saying if I use the single prong switch is to wire the hot wire to the switch and take the other wire and run it to a ground on the engine or frame.

This pix I drew may help.Essentially,you would leave the wiring original.The only difference is you use only the fan wire.The ground wire that's in the 2 prong plug is not needed.

The part # 37750-611-154 is the temperature gauge sender not a single prong temp switch.
The correct switch is available on Ebay for $39.
If it was that easy everyone would be doing it!

is there any way to check if the fan and thermometer are working without heating up the bike? It is still really cool here and I would like to know if it is working or not before I find out the hard way.

You can check the fan by removing the black rubber plug and bridge out the two (green) & (black) wires with the ignition on.
You will need to remove the switch from the thermostat and heat it in oil to test it though. You will loose some fluid.
