Yeah, I had tried a typical off-the-shelf cord, probably 14g at most. At the time I didn't know any better. I was told, back then, to get/make a larger cord.
Another time I thought the compressor had failed or was faulty, I researched the different parts and functions, trying to determine which part I needed to replace. Come to find out the female coupling was clogged or stuck closed.
