RESOLVED
I picked up this air compressor and the seller said the motor was bad. I powered it up and it ran briefly. After checking, I found the capacitors were bad, and it looks like someone had already replaced the run capacitor at some point. I installed all new capacitors and wired everything the same way it was before. Now it runs longer, but then it burns out one of the start capacitors and trips the breaker.
I also need help making sure the wiring is correct. Any ideas on what could be causing this?
