I've not posted lots on PEF but have greatly benefited from the knowledge shared here. Great forums. On to my issue...I've have a HF Predator 3500 whose display won't show anything but hours. Somebody else posted with this issue, but I don't see they ever figured out a solution. I pulled the panel and all seems to be hooked up fine. Maybe a wire loose on the generation side of things? For voltage, current etc., it just shows zero. Generator works fine, just can't see the voltage it's putting out or the load. Any thoughts? Ways to test the screen? Thanks for any ideas. I would love to fix this before we have some Public Safety Power Shut downs. Thank you in advance for any ideas.
