Hello, thanks for taking the time to check out my question. As the title states, I have a set of fans that I need to know how to test. They cause the battery cables to get very hot when running, when the AC is on or the fans kick on due to the engine warming up, the positive cable on my battery and the alternator wire get fire hot. I'm pretty sure that there is a short somewhere but have issues isolating it. The fans will kick on high and low speed when the AC is running but from what I can tell they only run on low when the car heats up to operating temp. I have replaced everything in the charging system and still have no luck getting this working. Is there a ground for the fans that I can check or maybe something with the fan control module? Any advice would be appreciated!
