So I got the tank back up to pressure again, and same thing, struggles to start, eventually trips breaker. I loosened the compression fitting on the transfer tube from the head, and while there was no active air rushing out, when I threw the power switch, it fired up immediately and effortlessly. So does that narrow it down to the check valve? Might I have gotten a bad one? If that it, this $100 pressure switch is going back! Thanks

Thanks MTR...yes, this is accurate.

I shot a quick video to show you what its doing. If I loosen that discharge tube, the motor fires fine, no air leaking. But when I reattach, the motor just can't turn over as you'll see in the video. Thoughts?

Great, thanks, I'll give it a shot!

MTR - so I got into the plastic motor shroud which houses the Caps, and looks like the starter/centrifugal switch. I starter going towards the start cap, and going to discharge and test...but while I was I noticed the switch. Does this look right (see pic) - there is not a contact post (or whatever you call it) on the left side of the switch. Clearly this is a cheap motor, or inferior to the all metal one you show in the PDF you sent me, but the concept seems the same. But, does that look right that its only on the right side, or do you think it broke off on the left. The only thing that has me question whether its normal or not is that on the right side in the pic, at the bottom of that post/flap, there is a copper contact beneath it, but that copper contact doesn't exist on the left. Let me know your thoughts. If you think that looks normal, I'll keep moving on to troubleshooting the next items - if not, is this even replaceable? Almost looks molded into the plastic shroud. A Google search on this model doesn't really bring anything up since this is an older compressor - parts seems very limited. Thanks!
