Brain meats taste good
Past fortnight or so I have noticed the temp climbing while riding around in town traffic. Found out that the fan temp controler thingie in the base of the radiator is not working by shortcircuting it. This is the second one that has needed to be replaced. Any ideas as to why/how?
Alternertivly does anyone see any problem if I wire the fan up so that it will always be on with the accessories?
Cheers

gee wizzz
Wonko --no prob fan being runnin on accessory but the better way would be to pull the wires of the temp probe and just wire in a simple on off switch to the wires exposed.

I thought about wiring in an off/on switch, but i would be another thing to have to turn off after a ride as it is a direct conection to the battery. ie the fan should normally still run after the bike is turned off.

are you sure you're shorting the right temp sensor thing? on my zeal, it has a sensor on the radiator that activates the temp warning light, and then another one near the thermostat that activates the fan.

Yeah I ahve the right one, I can unplug it and ground it and the fan comes on like a charm.

And to keep in on topic, completely different bikes that is. Are you sure it is getting hot enough to warrent the fan? The reason I ask is I know of other bikes with fans that get perdy darn warm before the fan even think about cutting inOriginally Posted by erik

Orrrrrrr, how about an auto type sparky checks the switch/sender unit to see if it is operating?
toadily mad
we have had this issue with two of the hondas we have owned, the sender unit that causes the fan to kick in at a given temperature crapped out so we did as frosty suggested and wired manual switches, just turn em on going uphill or in traffic and otherwise turn em off, works fine and again as frosty says, better that than a blown motor eh!!

:spudwhat: Why would you want the fan to run if the water pump has stopped?

keeps the radiator comfortable???

I'm not 100% sure why the fan keeps on going after the bike has stopped. I belive it is to help with cooling the bike down.
Water will still flow around the cooloing system due to thermal dynamics. air flow over the radiator will cool the water down in there. Hence cooling bike quicker.

Without seeing a wiring diagram for your bike I can't really say for sure, but that just doesn't sound right - most bikes stop everything immediately when you turn the key off. Maybe a previous owner has done something which is giving rise to your problems???

That is possible as it has been stripped down and rebuilt(or so I've been told). The main loom looks intact, and the connection looks original, but the last 6 inchs of wire to the sensor have been replaced. A switch may be the answer, but will have to wait until after I've moved and unpacked.

At least for some bikes it's normal for the fan to still run if the engine is really hot when the ignition is turned off (eg, it says it is for the FZR400 in the manual). And I'm pretty sure I've read the same thing about the radiator fan in my old car.
