Transfer Switch
Fired up the generator yesterday while on shore power, showed voltage output on both legs but no switch over to generator. Disconnected shore power and same problem. Probably defective transfer switch but would like to know for sure how to tell and where would one likely find the switch. Also, can one manually make the switch. Have '08 36' Mid-door. Any body with ideas?

Were the circuit breakers on the genset off?

What circuit breakers are you referring to because the voltage panel beside the Xantrex control panel inside is showing voltage of 123 on both legs. I am aware of breakers on genset but didn't think would get voltage reading if open.

You are probably seeing both legs of the shore power on the surge guard display. At least mine shows 2 lines of voltage with the gen not running.

Actually, reading voltage on shore power and when disconnected, reading genset voltage. Will try breakers tomorrow. Thanks for help and will advise outcome.

Probably the transfer switch then. Mine is in the ceiling of the front bay just behind the water tank.

My transfer switch is in the electric bay. The original swtich "stuck" a few times. If I would thump it as hard as I could with a closed fist it would switch over. The original switch was destroyed by a lightning stike a couple of years ago, and the new one has never stuck. One way to keep the transfew switch in good condition is to shut down all the loads you can before plugging in/unplugging shore power and/or starting the generator.

There is usually a 2 year warranty on the transfer switch. Yours might be covered depending on what month your rig went into service in 08.

SC- my xfer switch is contained in the black SurgeGuard box mounted to the frame/ceiling of the utility bay. Open the utility bay, then open the large door and it should be above to the right of the Xantrex inverter/charger.
There is also a transfer switch in the inverter, and much of the interior 110 is off that transfer switch. Could be that loads you checked are off the inverter and that xfer isn't xfer'ing. Check the plug behind the passenger seat (which is not off inverter) for 110V; if you have juice there but not elsewhere and gen is running then the inverter xfer is suspect.

Thanks to everyone for suggestions. Moved coach tonight from temporary parking at Wal-Mart to storage parking. So close to home and convenient to park for several days and unpack slowly. Checked the breaker at genset and was on and again showing both legs on inside panel but didn't have Engineer Mike's most recent post about the plug behind the seat. I did speak to Xantrex tech support yesterday and they also mentioned their transfer switch but much harder to test than E-Mike's suggestion. Will try the a/c plug behind passenger seat tomorrow.
