Autoformer Voltage Booster Question

If the booster does not pass through power there may not be much you can do.
Inside is just a transformer, circuit board and a relay. You could open it up and take a look for something burned up. There are a few repair guys that pop in here that might be interested. Shipping might be a bit much for an unknown issue.

Polarity was checked with The Defender Surge Protector previous to plugging in Frank's Autoformer.

If the trailer is metal you can have a "hot" skin situation. This is not just undesirable, it is dangerous. Hot skin may work with other devices in your RV, too (for example a metal toaster).

Did you check polarity before plugging in? And did you check polarity at the "2nd" pole as well. It is entirely possible for the entire campground loop to be reversed.

Need voltmeter to verify.

I have my RV plugged into this and all is wellDefender Surge Protector

So what's the deal with reverse polarity?

If the other pole is coming off of the same feed it could be reversed also. Depends where the mistake was made. Try it in another section of the campground.

Either way don't throw it away. Offer it to somebody with a 30 amp and let them try to sort it out.

You do know that everything will work with the polarity reversed, right?

Seems odd. How did you verify polarity? 30/15 adapter with a 3-light tester?
I have a Frank's and I was not even aware that polarity check was an option.
And yes Frank's is long out of business.
