I have a 2002 Ford F150 supercrew with factory tow package 7 way & 4 way. I installed a brake controller Hopkins Agility and adapter pigtail. Plugged it into the factory plug under the dash. Break controller indicated there was a trailer connected when there was not. Checked the 7way, it had water in it. Dried it out, checked trailer brake contact in 7way plug, test light was faintly illuminating. Checked with volt meter, it showed 4.5 volts on the trailer brake leg of 7way plug. I dont think there is supposed to be any power on the trailer brake leg of the plug, when the brake controller is in standby mode, vehicle off, and no trailer attached. When you press the manual override switch, the brake lights on my truck come on. Is that normal? Brake controller is not displaying an error message. I am thinking I have a defective brake controller. Any advice will be greatly appreciated. Thanks in advance.
