We won't leave you hanging on this one. My computer was down with a bug so I am just now getting back to you.
First question. Can you run on the generator when this condition happens?
Now, you will need to remove the cover from the service panel in your coach. With the shore power plugged in measure the voltage across the main breaker. This should be 240VAC. This is simply a verification test of L1 & L2. Your coach is a 120A unit so you next want to measure from one side of the main to the NEUTRAL
. This should read about 120VAC. Now read again to GROUND
. It should be the same. Repeat these tests on the other leg of the main. Repeat this testing on the service panel buss: 240V across them, 120V from each buss to neutral, then ground.
Let me know what you find. We will go from there.
