I had a wav 118-60 that wouldn't power up. When you turned the key on the display or battery meter wouldn't light up. I checked fuses, plugs, power to the contactor and controller but it just wouldn't power up. I don't have access to Crown manuals so I told the owner to get a Crown tech in. He did they used an analyzer worked on it for 8 plus hours. They came to the conclusion that it needed a new wiring harness. Could it be the contactor for the hydraulics?
