Evo Cooling Fan Wiring Diagram Lancia Delta HF Integrale

Here is the cooling fan circuit wiring diagram for Evo Lancia Delta HF Integrale. This is two speed radiator cooling fan. For the operation, the fan(1) is controlled by the two stage thermal switch(2) which as the first stage9a) closes when the temperature of the engine coolant reaches 86-90 degree Celcius, allows the flow of current from the battery to the fan(1) ia the resistor(3) thanks to the energizing realy94) closed to earth operating the first speed of the fan by closing its contacts. The resistor93) is protected internally by a thermal contact(s) which interrupts the electrical circuit when the temperature exceeds 130 degree Celcius. When the temperature of the engine coolant reaches 90-94 degree Celcius, the second stage(b) of the thermal contact(2) also closes putting the relay feed(6) energizing circuit to earth and the latter, by closing its contacts, sends current directly from the joint to the fan without passing through the resistor(3), thereby engaging the 2nd operating speed.

    i always prefer to use brushless cooling fans because they last longer and needs less maintennance-`-
