It had something to do with trailer I had. I was pulling mining equipment which had its on engine and battery grounding its lights thru the trailer. I did have my own lights but they must have grounded into trailer as well. It shorted something my right turn hazard and high jake would work for a few secs, then quit. Signals would reset but jakes wouldn't reset till I turn the key.

I dropped the trailer and everything back to normal.
Thanks for finding fault but if something was really wrong.

****How do you test the wires?****
