Good morning. I recently purchased a used Devilbiss air compressor. I connected it to an existing 230 line that was previously used for an RV connection. I connected it up as seen in the images and it ran great for 30 seconds then acted as if it was only getting 110v then smoke appeared from the end of the motor. Checking the power, the black line is providing 120v and the white line is 110v. I have no idea and am hoping for some suggestions.
