Only test at the ATS if you are safe working around 120VAC (30 amp) and 240 VAC (50 amp)!
Remove lid. There will be two sets of wires coming in-- one from shore power and one from generator.
With everything off/disconnected, verify that all wires are clean and tight.
Start generator and check between black wire (hot) and white wire (neutral) and green wire (ground). Should read 120 VAC. If 50 amp, check between red and white and red and green as well. It also should read 120 VAC.
If you do not have 120 VAC at the ATS with generator running, check the connection where the generator output is wired to the coach wiring.
