Thread: Help!!!!

So I just installed my MAstero shutdown controller. It works fine but for some reason the fan in my Keypower power supply wont spin. When i turn car on everything goes on but there is just a loud clicking noise from the power supply and the fan tries to spin but doesnt. It worked before the shutdown controller was installed. I ahve 10 ga wire throughout and the keypower and shutdown controller are grounded via a distrobution block. What gives?
