I have been exploring the compartments of the class A my husband and I just bought. I have found a mysterious device next to my electrical hook up equipment. It looks like a plug that would go into a 30 amp outlet, but with no cord and what looks like two small electrodes on the side opposite the plug. Is this some kind of polarity checker? If so how do I use it?
Thanks for your help!
