Welcome to the forum. Usually the generator starts by using the house batteries to start it up and run. Start looking at the house batteries. There should be another breaker at the house batteries that might have tripped. You need to look into the house battery box to find that breaker. If it was tripped there will be either a red or yellow flag showing. You just need to push it back in to get it working again. Not sure by what you mean you are using the cord that came with it? Do you mean the 30 amp 3 prone power cord? Are you plugging into an adapter to plug into you home to supply 120 to your motor home? If so, sometimes the home outlet will shut off if it is connected to a GFCI. If it is throwing the breaker inside your coach, there is something wrong with the incoming voltage through your 30 amp cord to your house. You need to work backwards from the house to the cord to the motor home to the breaker to determine where the issue is located.
