i need to find the trigger wire for the fan relay. i think its pin 3D. is this right?
and at what temp will it kick in ( so i can check it before hard wiring it.)
I\'d imagine it would kick in around 80-82deg
the thermostat isnt even open at that temp so i would have said the fans will come on after. i think its between 95 and 100 but want an exact figre so i know when to check its live. or is it switch earth?????????
was playing with it today and it goes live at 100c but only gives .5v so wont trigger the relay. any ideas?
You should have one terminal on the relay being powered by +12VDC, the current form the thermostat should simply cause the relay to switch. I\'m assuming you have a N/O relay and not a N/C relay? (Sorry if I\'m teaching you to suck eggs here!) I found that nicking the relay off of another vehicle worked very well, is this the case for you? Or have you gone to RS for yours? Most non-automotive relays are either 24VDC or 230VAC switching. Might be worth checking...

???? no idea what that is. if it means the fans work with the trigger wire on live, then yes it does. lets asume it is a 12v relay (it should be but i haven\'t gone down to double check it ) would that trigger with the .5v from the ecu?
i was sure i had the right pin from the ecu but it isn\'t working so wanted to ask everyone if that was the correct one. if it is should it be more than half a volt?
