Trailer light hookup issue

My brake lights on my trailer are not working so I thought I would check the pins on my truck first. When I press on my brakes I get no voltage between the ground and brake pins. So I go check the fuse and it is good. Check voltage to the fuse and I see 12 volts. When I have the brake pressed down my left and right turn signal pins have 12 volts constant. Also voltage to the turn signal pins are intermittent when turn signals are on. Has anyone had an issue like this?

 

7 or 4 pin plug and if a 7 are you using a brake controller? If 7 and no controller, sounds right.

 

Yeah, I screwed up. I was checking the brake pin for brake lights when I should have checked the l/r turn. All is good. I was here trying to delete this thread when you posted.
