Thanks, all. I just came back from checking the actuator-it’s full. I am going to go back and clean up the trailer side of 7 way plug. I had put some electrolytic grease in it on advice from my Ford dealer, then proceeded to drop it in the dirt. I bought some electrical connector spray and will check it after cleaning. I could have sworn that I could stop forward motion at slow speeds by manually applying the brakes. I ordered a new 7 way pin checker, but got delayed due to weather. Going to check brake and ground pins on truck for output.
