Batteries not charging with shore power

[SilasMarie]

Hi,
I have my 2017 Sunseeker plugged into my home power. The cord lights up with blue light to show the electric cord to the motorhome is working. However, there is no electricity to the house -- lights and AC not working. With generator on, I can get both to work. I checked circuit under bed and nothing is tripped. What am I dealing with? Thanks!

Do you have a transfer switch or a generator outlet? If a transfer switch, give it a wrap with something to see if it is stuck. If a generator outlet, the problem is your home outlet

So it appears that things work if you get 120 volts out of the transfer switch. So the problem must be in the power path from the receptacle you are plugged into and the transfer switch output. Possible point of failure include:
The receptacle
The shore power cord
The shore power cord reel if you have one
The sore power connection into the RV
An EMS device in the shore power path
The transfer switch
Any adapters you are using

Use your multimeter to test for each and every connection from the receptacle up to the transfer switch. Verify that you have proper voltage at each connection!

How are you plugged into your home power? If you are plugged into a 15/20 amp GFCI outlet on your house with an adapter on your power cord the house GFCI could be tripped. The rv has GFCI outlets in it and being plugged into one at the house will cause the house GFCI to trip. GFCI's do not ply well together.
