All of this is more than getting the compressor running. I want to understand it and learn from it too. I can forsee having to contend with another magnetic starter in the future. I appreciate everything everybody has done for me especially you running the gauntlet with something more controversial. It wasn't what I was needing at the time but if I had the parts I might have broken one leg temporarily to use the compressor in an emergency. I had to order a replacement pressure switch so I'm not going to be doing any permanent wiring until the end of the comming week.
One thing I will never understand is why they don't just make a heavier duty pressure switch.
