I recently hooked up my trailer to my truck and to my suprise I threw the 40 amp trailer fuse. After blowing two more (at $2. 99 each) I got the meter out and went to checking. All seemed to be working fine with one exception, The terminal on my truck plug for the brakes is constantly reading 11 to 12 volts. Should this terminal always be hot? After unplugging my brake controller and replacing the fuse again all the trailer lights worked properly. The tech at Jordan said there should always be power there, but this just doesn't make sense to me. Any help or advise will be appreciated. I should mention this is on the factory 7 pole plug mounted on the drop hitch.
Thank You,
PS. I hooked my brothers truck up to the trailer later and his controller seemed to work fine.
