I've been playing with a new rad temp sensor today as I want to do my own wiring for the cooling fans
It's a 3 pin rad temp switch which was about 3 quid off eBay
Using a thermometer, multimeter and a kettle I have worked out what each pin does.
Basically one of the pins is where you connect your input (be it 12v feed/earth) and then one if the pins becomes live at 82 degrees and the other at 85.
Plan is to wire fans up so that at 82 degrees one fan comes on and the other at 85. I'm also going to wire in a manual override 2 position switch so I can have one or both fans on at any time.
