I Know SQUAT About Spraying Automotive Paint.

Hi Warrior!

Thanks for the advice everyone. I was gone for the weekend and the new switch arrived while I was gone. It's an eBay item, it was affordable but I have no idea if this is a good name part for these switches. But I t's a waay better quality part than the Harbor Freight item it'll replace. I just have to figure out how to hook it up - oughta be a cinch - and it ought to work fine.

EDIT: Oops, I went back and re-read. The other issues means I didn't say figured out why the unit wouldn't run? Yeah, I connected the wiring incorrectly! Once I fixed that I let it cycle three times up to 150 psi/down to 120 psi to turn back on. No issues that I detected other than I had to manually disconnect the power to make it shut off.

The original pressure switch is controlled by a cheesy plastic dial type "switch". When the plastic "hinge" on this cover cracked it no longer held the lid/switch thing in position to control the on/off.
