How to Fix an Air Compressor that wont build pressure

In today's short video we decide whether or not its time to scrap our trusty yet continually faulty Husky 80 Gallon Air Compressor.
After we fixed the check valve and the electrical contactor in previous episodes we have yet again had a failure in this air compressor shortly after we finished our Rapid Air pipe installation series.
After spending a ton of time installing the Rapid Air System along with new Regulators, filters, coalescing filters, desiccant air dryers, reconnecting our refrigerated air dryer, adding brand new Tekton Hose reels for our shop air system having a broken air compressor isn't something I can handle.
We're going to take some time to diagnose this failure today and see if we can fix and repair this air compressor once again and get the shop back up to operating speed.
