Trinary Switch Wiring With Dual Fans Dual electric fan activation with ac trinary switch both fans. if you have multiple engine fans, and would like to have the option of turning them on simutaneously, use this setup. both fan 1 and fan 2 are activated by the temp switch, the a c trinary switch, or the manual override switch. note: typical ground trigger trinary switch. I then added the trinary switch, resistor, and diode to the diagram. i wired this up last weekend and here is the sequence of operation: coolant temp reaches 195, fan #1 comes on full speed. coolant temp reaches 205, fan #2 comes on full speed (fan #1 remains running). trinary switch closes, fan #2 comes on full speed.
Electric Fan Wiring Help Team Camaro Tech The trinary switch does that. all you need to do is wire the trinary switch output to the fan relay(s) for full speed. i don't have the schematic for the spal controller, but it may have been posted here previously. maybe somebody could post it or a link. it shouldn't be too hard to determine where to connect the trinary wire. A trinary switch will allow your electric fan to turn on and off based on either engine temperature or ac system demand. keep your engine and yourself cool b. The benefits of using the trinary switch to control the fan rather than having the fan come on only when the a c clutch is engaged is as follows: 1. if the natural air flow from driving down the road is sufficient to cool the condenser, the radiator fan will not run (unless engine temp dictates it), which saves wear and tear on the radiator fan. 1. enhanced cooling efficiency. the ac trinary switch wiring enables enhanced cooling efficiency by allowing the air conditioning system to adapt and adjust to different operating conditions. this switch is designed to monitor both the pressure and temperature of the refrigerant, ensuring optimal cooling performance.

Vintage air, pcm wiring to dual fans. ok hopefully i can make sense!!! i have an ls engine, vintage air and dual fan setup. the pcm has 2 relays in the aux standalone harness fuse box (fan 1, fan 2) and 2 red wires coming out of aux fuse box, 1 wire going to each fan. i believe it is programmed for low high operation. Step 5: test the ac system. once the wiring is complete, it is important to test the ac system to ensure that the trinary switch is functioning correctly. reconnect the negative battery cable and start the engine. turn on the ac system and check for proper operation of the compressor and condenser fans.
