1990, 80 non-Q- 3A eng. I would like to know the ohm value for the series 
resistor for the Radiator fan. Also is there a way to check the 3 prong 
thermal switch, located at the bottom of the radiator, below lower radiator. 
What pin should be open/closed when the engine is cold?
The fan runs when I turn on the A/C, so I know the motor is good, but....
I checked the cooling sensor for the fuel lines, next to the head/intake 
manifold, it's OK.
