Re: Rad fan sensor ideas

A: The company that makes aftermarket fan blades (I have a migraine and 
twisted neck/shoulder pain today, even after a visit to the chiropractor so 
I can't think of it, but sort of like Haines) Duuh! Hayden! makes a 
universal sensor you hook through the rad fins and it comes in pre-set or 
adjustable.

I put the radiator in the American this weekend with it's electric fan in 
place, Tight fit!.
I have a relay wired up in the relay center to power it.
Now I'm trying to figure out how to trigger the relay.
No place in the engine to add a sensor that I can think of.
My options are, to use the relay I have in place and trigger it with a 
switch. Then I would add one of the adjustable t-stat systems as a main unit 
and use the switch as backup.
The other thought is to get a piece of pipe and put a bung in it and use a 
threaded snsor to trip the relay.
   Anyone have any thoughts on any of this?
Anyone know a good source for a threaded fan switch?
Autotronics makes a nice one that has a ground wire that would be needed 
with the radiator hose mount, but the sensor itself is $80!

Thanks, guys
