That system can be difficult to sort out . I had issues with mine and found that grounding at the pump and solenoid was the main trouble . Every mechanic checks for power , but the loss of grounding is very common . I replaced rocker switches and set up a bus bar for grounding at the pump in the lazzerette . If you are hiring people call a hydraulics overhaul shop , they understand these systems . Really its similar to a snow plow set up .
