Automatic transfer switch

[wynedge]

I just got back from a trip , and went to plug my mo-ho to my own power so the fridge could use that instead of propane till I could empty it, and I hear this loud clickity clacking noise that seems to be coming from the Automatic transfer switch box. It worked fine at the campground. Any Ideas?

Might be the relay contacts aren't making good contact in the transfer switch. With the rig unplugged and generator off, try cleaning them with some emery cloth (or fingernail file). Also, if you're a 50 amp rig, make sure your power source has power on both legs.

It could be low voltage too, it takes 110 volts to hold the transfer contacts closed when on shore power. Check it and see if OK.
