Fans not work
#1 · July 10, 2019, 6:19 pm
hi
I need a little help with my electric fans, I have a 400 hp system with FCC 2, connect everything according to the instructions provided by Fitech, but I can't make the fans work, even change the temperature sensor by the ac delco, which I need to do to make them work.
I leave some images of what marks the screen
Thank you

The yellow wire for fan is a ground trigger for a relay. You must use a relay with 12v power going in and the yellow wire as the coil ground. Then 12v going in to the switched side and fan coming out. Other fan wire is grounded.
