There may be a voltage monitor circuit in the generator that is not working properly. At any rate, this situation identifies a "potential weakness" when operating a generator without an ground plug (neutral/ground connection) and putting the EMS in bypass mode so it will allow the generator power into the trailer.... It also identifies a weakness if no EMS is connected and the operator is relying on the generator to "protect the RV electrical system"...

This situation, 97VAC on the trailer input power, will cause damage to the Air Conditioner, the TV, microwave and any electric motors or possibly other A/C powered equipment in the trailer.... It may also do damage to the generator winding if the amperage goes too high and the monitor circuits don't shut down the generator.....
