Having talked to Billy at Outdoor dog supply, seems our troubles are coming from where we pared our boxes together. I guess it automatically sets it at 2.5 seconds just like the collars. My buddy already changed his to 2 mins and problem seems to be fixed as far as staying on when plugged to cig lighter. He says he still can't Tone or Shock, but at least it isn't cutting off and on. Thanks Billy, I can hardly wait to get home and correct mine.
