Well, I am just about fed up with electric fan controllers. I built a duel electric fan set up for my big block dart. I ordered a derale duel electric high amp. fan controller. was not cheap. $137.95. Got the first one all wired up and the controller was defective right out of the box. the fans would not come on at any temp. the manual override feature worked intermittently. So I called and they sent me another free of charge. Got it all wired in and it worked great for about 190 miles. thought I had the cooling system done. Well yesterday i drove the car to work. 22 miles each way. Worked perfect all the way to work. Took it out on my lunch break and it worked great. Hop in the car to go home and about 2 miles down the road and im at 200*. i shut it down and took a look at it. everything looks fine but fans wont come on. the Manuel override function works but only drives one fan. I limped it home on the free way and kept it down under 190*. I called Derale again and they think the temp. sending unit is no good. FML. Now i will be taking it all back apart and testing the sending unit.
