Default Transfer switch issue?

I have not been plugged into show power for at least 6 months or longer. I run the generator weekly to charge the batteries.

This last weekend we decided to stay in an RV park. I plugged in with the 50 amp cord. I turn the transfer switch from "gen" to "50 amps" and couldn't get any power. I then turned the transfer switch to "30 amps" and got power on leg one only. No power on leg two. I then unplugged everything fired up the generator moved the transfer switch to "Gen" and got power on both legs. I then tried the 50 amp shore power again and got the same results. No power when switch to "50 amp" and only leg one when switch to "30 amps"

So my question is, does "30 amps" only power one leg? I guess my water heater is powered on leg two, because we did not have hot water and some of the forward electrical outlets did not work.

Does this sound like my transfer switch is bad?

Any help would be appreciated,

Thanks,

Yes one 30amp line will only power one leg. My 83 PT has two places to plug 30 amp service into so it will power both legs. Yes it sounds like the transfer switch is bad but I've not dealt with that issue as of yet.

When the transfer switch is set to 30 it connects the two 30 amp receptacles, one to each side of the breaker panel. When it is set to 50 amp is connects both sides of the 50 amp receptacle, one to each side of the breaker panel. If you get power when set to 30 amp, your shore line is plugged into one of the 30 amp receptacles.

Your 50 amp shoreline will have a 4 terminal plug on the pedestal end, the 30 amp plugs have three terminals.

Yes, the bus came with two power cords. a 30 amp and 50 amp. Both power cords have a 50 amp connection into the bus. Both are tagged with red tape.

Since I owned the bus (6 years, boy does time fly), I have never plugged anything into the 30 amp connectors. To be honest I never even new what the two inlets that are located above the inlet with the tape on it was for. The previous owner told me to only plug into the 50 amp inlet which is marked with the red tape.

I should have disconnected the 50 amp cord and tried the 30 amp cord to see what happens.

Yes. This picture shows how I had it plugged in. But the transfer switch only worked when 30 amp was selected and only leg one. I could not get any power with transfer switch was selected to 50 amps.

Yep, my power cords have connectors just like the picture you posted. 30 amp is yellow and 50 amp is black. The receptacle that plugs into the bus on both cords are 50 amp and both are tagged with red tape.

I will need to take the bus to another RV park and do some trouble shooting. I am kicking my self for not trying the 30 amp power cord while I there.
