Generator Issue

Helping a buddy work on his Coach. Thought he was having a problem with his Transfer Switch because he has power when hooked up to 50 amp Shore, but when dry camping the genny will provide power sometimes and then nothing. All breakers are good, both on the genny and in the coach.

Tested the power to the transfer switch and it's good, so assumed that the switch just wasn't flipping over to provide power to the service panel. Replaced the Transfer Switch and the problem didn't go away. Still have genny power at the switch, but nothing into the Coach.

What are we missing here?

    When you checked for incoming power to the transfer switch from the genset, did you read two legs of 120 volts to the neutral from the genset?
    Did you check for two legs of 120 volts leaving the transfer switch going to the 120 volt distribution panel?
    What is make and model of genset. Is it 120/240 or two legs of 120?
    Does the rig have an energy management system?

    Could be the voltage regulator. Had same symptoms on a Onan 5000 a couple of years ago and that was the fix.

    If you post the brand, size/model number you will get a lot of good troubleshooting tips.
