Just wondering how many people run a manual fan switch? Sick and tired of the fan fuse or switch located under the seat on my kawasaki not working properly. Sometimes it works, sometimes it doesn't and I've replaced this fuse or whatever it is twice. Think it would be simpler just to run it with an on/off toggle switch. Let me know your thoughts

my '98 grizzly has a fan on the oil cooler...... It is factory wired with the temp sensor, but has a manual overide switch(lites up, when fans turned on) so i can turn the fan on when workin' it hard..... No guage, so it's still a guessing game. Switch is easy to get to....

lots of people are swapping out the fuses for circuit breakers.

if in dry conditions, won't hurt to leave it on..... But wet conditions, be careful..... Don't want the fan splashing, when cruising through creeks etc.... I just feel the heat, so easy enough to turn on the fan...... Mine does have the warning lite if gets too hot, anyway. safest way is if you have a temp guage(like koso) or something to be certain you're not overheating anyway

run one on all my popo's. usually can tell when the bike is hot enough to turn it on. i turn it on whenever i come out of a mud hole just to cool off the bike and to also make sure there is no swamp grass or something plugging up the fan.

i just put one on my brute last night.... easy to do.... just have to make sure that u have a 15 amp switch at least and i put in a 15 amp fuse to thats seporate from the rest..... went right from the starter silonoid main batt wire...... ran to the switch then piggy backed to the power wire of the fan.....

My concern is when forcing power to the fan you are also forcing power back to your ecu or some where. Anyone thought of a diode on the power wire so it doesn't feed back?

ya but ur not forcing power back to the ecu.... cause there is 2 ways it starts the fan..... either it turns the relay on [ which is a seporate circut ] or sends power out from it with its own relay onside... same idea... unless the relay's on and the switch is on are they conected..... but power only flows one way when the circut is grounded.....
if ur all concerened about it just put in a relay seporate.... most relays now have diodes built into them

Ya I'm not that electrically gifted.. Ha was just going run new wires from the fan to the battery, with a switch and fuse in between. I assume the fan just runs off 12v power so I think this would work... This way it's in it's own seperate circuit with no chance of a screw up

It's most likely ground switched through the sender in the radiator, all you have to do is splice into the ground wire at the sensor and bypass it.
Leave everything stock, just run a new wire, so the fan electrical will use factory relays.
What does the manual say I gave you?

kawi 's are ground switched to the ecu but then sometimes have problems with the breaker...... so thats y u run the power wire to the fan just in case the breaker and such do not work u have a back up then....

So I got out the repair manual, sat down to try and figure something out, and then noticed one wire was not connected to the switch that is in the radiator... Connected it and away I went... Boy I felt dumb!!

add the fan switch too....... just so u can over ride it when the stock stuff doesn't work..
and you can wire the other end of the original fan circuit (ground or power - whatever the stock relay turns on) into a light on the dash. When the stock relay trips like it would to normally turn the fan on, the light comes on instead. Then you just flick the switch to turn on the fan (if its not already on). This is what we did with the hillclimb bike, works good.
