Or a single relay could be used to control both fans. Wiring dual cooling fans.
Electric Fan Wire Diagram H1 Wiring Diagram
How to wire dual electric fans diagram. Electric fan relay wiring diagram wiring diagram is a simplified tolerable pictorial representation of an electrical circuitit shows the components of the circuit as simplified shapes and the capability and signal contacts between the devices. And if a relay fails you will still have one fan running. It uses a 40 amp electric relay and electric fan sensor. Start your wiring project by taking both of the positive wires from the fans and run them to the yellow wires on each relay tab 87. This is based on the draw from the fans if the fans are larger and draw more than 15 amps each its recommended to install a second relay kit as shown below. However two relays will divide the load.
It uses our 40 amp electric relay kit part number 91064044. You could use one relay. There are several ways that a dual fan can be wired. With dual cooling fans there are two methods for wiring up the relay kit. How to wire dual electric fans diagram wiring diagram is a simplified standard pictorial representation of an electrical circuitit shows the components of the circuit as simplified shapes and the facility and signal links amid the devices. The cooling fan wiring diagram below is what weve found to be the simplest and most reliable method.
Primary cooling fan dual fans with dual relays single speed onoff using ground switched devices only for primary activation using dual relays for two fans is not required. Or a single relay could be used to control both fans. For example dual thermostat switches or dual relays could be used to control each fan separately.
