When you jump across it, you are shorting out the circuit - commonly used for testing components to see that they will turn on. When everything is connected the way it should be, there is also a thermostat which comes into play in the circuit - unless the thermostat gives the "command" for cooling, the fans will not start up.
I have seen this before more than likely your coolant sensor has a internal short and needs to be replaced.
This is just an idea, try flushing your cooling sytem. When was the last time you flushed out your cooling system?
The duration of The Princess Comes Across is 1.27 hours.
The wheel comes off first then the caliper then the rotor just slips off. GoodluckJoe

Antec spot is one of the best product when it comes to system cooling. This product features great fan cooling features and it is energy saving.
your thermostat is most likely stuck open. replace it ,,before ol' man winter comes!
first check to make sure the fuse is not blown. If its not then there is a fan relay that will need to be replace and it cost around 15 dollars.
When 1990 Honda is running cooling fan does not come on but comes on when engine is off and I thermostat and temperature switch changed?"
I don't think you have a problem unless your temp gauge or light is coming on. The reason your fan comes on after you shut the car off is....... as you are driving and the car is running at operating temp, the air is flowing across the radiator cooling the coolant that circulates through the engine and radiator. When you stop, the water pump no longer circulates the coolant and you no longer have air flowing across the radiator fins cooling the coolant either. The electric fans are set to run off a relay, and when you stop, the fans come on to cool the coolant down until it cools to where the relay kicks off and the fans stop. However, the cooling fan should not come on each time you shut the vehicle off or if you're idling like mine did. If it does, you may need to replace your thermostat or you may have air in your system. Replacement of the thermostat is simple but be sure to buy the OEM from the dealership. My experience has been and the dealership has confirmed, that the aftermarket thermostats do not work well in these vehicles. My local dealership also advised that once the work on the cooling system is complete, they run the vehicle for no less than 1/2 hour with the radiator cap off. This allows air to escape the system. Since I have replaced the thermostat and "bled" the cooling system, my cooling fan only comes on during the hottest of weather.
The only thing that I've heard of with "wet cooling" in, is a wet cooling tower. A Wet Cooling tower for the closed-circuit cooling of water where the water to be cooled comes into direct contact with the cooling air dissipating heat by evaporation and air heating. The air draught required for cooling can be induced by fans or by the natural effect of the stack of the cooling tower building (natural draught cooling tower).So I don't know if that answers your question or not, but i hope it helps...
The frost comes, killing the mosquitos and cooling down the fever victims.
