I have purchases a used dynasty spa from a friend. Everything worked prior to loading it on my trailer. I have just connected it up at my house and it appears the spa disconnect keeps tripping. I'm not an electrician, however I am comfortable with doing the work. After tracing everything out with my multimeter it appears the hot black and white neutral are connected somewhere causing the short. My electrician friend is has not done hot tubs before and is unsure how they connect inside the spa itself. He has viewed all the wireing and I it all appears to be good.
