It has been an intermittent issue. I am fairly certain this is an electrical issue, considering the backup lights do not activate when the brakes don't dis-engage. I found wires from umbilical cord to the actuator that were exposed to the rubbing of the safety chains. These wires casing was worn off and exposed---guessing this was creating a short. I fixed and looking forward to testing this weekend.
