4500 Air Filter Light ?

[Bdavis]

I changed both air filters about 50 hours ago. I was doing routine maintenance today, grease, clean the engine and check the air filter.

The outside air filter was a little dirty so I blew it out. ( the inside was perfect). When I put it back together and start the engine the air filter light
on the dash board stays on. ( the book said that indicates a clog)
What is really funny to me is that the light comes on even before the engine cranks like when preheating and just stays on.
Seems like to me if the sensor was good it would stay off and only come on if there was no or little flow through the intake.
I will probably go ahead and replace the outer filter again but I think it may be that the sensor is bad.
Any one had any experience with this problem ?

No but if it happened after you "cleaned" it out I bet the sensor is dirty.

The light is now off. I actually think it took a few days to dry out the contacts from when I cleaned the engine. However, it could have been that I did not seat the filter properly or a little dirt. ( vacumed the filter and everything I could before firmly reinserting the filter.)

Next time , I clean it I will only blow and vacum around it and see if the problem reoccurs.
Thanks

This has happen to me, the sensor area holds water after cleaning the tractor, after the water dryes up the light goes off. I just just air to blow most of the water off after cleaning.
