Review on Derale 16789 Amperage Controller Thread by Jeff Drollinger

I found the product well made, but it is not waterproof, you need to install it in a place where it will not get wet. Another problem I found is a lock or switch AC only turns on a fan that my application is in. I wanted both fans to turn on with a lock, the switch is set and the Jeep 83 climbs rocks and I need the cooling fans to turn on at high RPM and at low RPM the fan turns on automatically but I would one prefer full overdrive
