AS35 – Fan switch wiring
Two Fans. Low and High Temperature
The diagram below shows the simplest way to wire up a pair of fans using a 2 pole, centre off toggle switch for control.
One Fan. Low and High Temperature selectable from the cab
The circuit below shows how to use our dual switch to control a single fan, but with two temperature ranges. Use the lower range while off road or towing and the high range perhaps on the motorway (more ram air cooling) or in particularly cold weather.
