NE SD | If they installed a power beyond AND return port, it SHOULD be a case drain and have a flat face coupler. Be careful and make sure you don't run the fans until you're sure it is a case drain. As mentioned, you don't want any back pressure on that line and the best thing you can do is use a flat face coupler to make sure it is never confused with any others. Some tractors, especially the 4wds with 5 or more outlets have more than one place to put power beyond returns. | |
