Spal fan relay wiring diagrams are essential for understanding how to properly wire and control Spal fans in vehicles. These diagrams provide clear instructions on how to connect the fan relay, power source, and temperature sensor to ensure efficient and reliable operation of the cooling system.
The wiring diagram for a Spal fan typically consists of the fan motor, relay, temperature switch, power source, and ground. The fan motor is the heart of the cooling system as it circulates air through the radiator. The relay serves as a switch that activates the fan when certain conditions are met.
Jun 13, 2009 · Run the two trans fans through a single relay, then through individual circuit breakers/fuses. This way if one fails, the other will continue to operate. Activate these fans either with a thermal switch or have operate when the ignition is tuned on. I prefer all fans to be activated via thermal switch or ECU, and not ign switch.
2) Pay Attention To Fan Loads And Splice Points: “Pay attention to current loads of the fans. Splices and connectors are common points of failure. It’s important to use a splice that is sufficient for the current load of the fan. Sealed splices are preferred.”. When you start to list all the things that can go wrong with your wiring, it ...

Step 1: Begin by identifying the power source for the fan. In most cases, this will be a 12-volt power supply, such as the vehicle’s battery. It is important to use a fuse or circuit breaker to protect the fan and the wiring from any electrical issues. Step 2: Next, locate the ground wire on the fan.
Apr 10, 2006 · For high current fans the best option is to supply power to them through a relay fed by the horn relay. Energize the relay with a small gauge wire from the fuse block, ignition terminal. Fuse both lines from the horn relay to the fan relays.
Dec 19, 2020 · SPAL fans move a ton of air. Their relay kit consists of a 40 amp relay and either a 30 or 40 amp fuse. I had issues with the 30 amp fuses on some of their beefier fans- they pull A LOT of amp at start up.
