Coolent Temp Switch - open or closed?
1988 420 - When the engine is cold what position should the switch be in?
Ohms - Cold ? Ohms - Hot ? My Elec fan runs all the time. I grounded the two wires to the coolent temp switch The relay clicks and the fan slows down. |

The blue 2 pin sensor is (NTC) variable & at low temps has high resistance.
