Just got a 5000- Watt Yamaha Generator. It puts out 120 V and 240 V from the pective outlets, but I get an "Open Ground" warning using a 120V test plug, and I only measure ~40 volts from either L1 to ground, and L2 to Ground, not the 120V I should be. I could also use a copy of the Manual(s). Thanks, Frank
