Anyone know what the ohm value should be for a standard (not twin fan) Wedge cooling fan? Thinking of simply jumpering out the fan on the battery to test if I cannont find the ohm value. Is this sound logic? Also, if I were to check the thermostatic switch, would I need to wait until the car actually gets to temp. until it can be checked or can it be checked cold?
I've checked the electric fan rely and 25 amp fuse, and all are fine. Seems that I have lost my electric fan and discovered it while sitting in traffic.
Your help is most appreciated.

Shaun,
Fans (and electric motors) have a very low resistance.
A 12 amp fan on a car would have a resitance of 1 ohm.
R = V/I
The correct way to test it is with a fused jumper, but almost everyone just sticks 12v on it!
Car cold - you should have 12v on one side of your thermostat, get it hot you should have 12v both sides of your thermostat.
If you don't it either needs adjusting if it's an adjustable type or it's dead!
