Voltage at the 50 amp plug was 120 and 240. The fridge was 50 degrees. checked voltage at fridge plug inside the coach was 109 volts. When plugged in to 50 amps coach meters read 123 volts on both legs. Plugged extension cord to a 120 volt plug in coach fridge returned to 36 degrees.
When unplugged going thru inverters fridge plug was 119 volts. When plugged in to 50 amp plug fridge plug was 109 volts. Fridge plug inside coach does not go thru the electric panel, it has a breaker in the compartment by the switch box. I have had two Prevost coaches, this is a new one for me.
