My colleagues and I have experienced several incidents which have all involved the WEU (Warning Electrical Unit) producing false warnings of various problems. There appears to be no common situation or cause, but thankfully our checklists involve resetting the WEU to confirm a real or "ghost" failure. If other operators checklists do not include this, it might be worth adding, to save shutting down a perfectly good engine ??.
