Two burnt motors within a short time means you need to ask first before hooking up anything.

However, I once had an engineer boss who burned up several expensive crystal oscillator modules by believing that he got a whole batch of bad ones.
He didn't. The power supply he used was defective so each new one he hooked up died within seconds.

Update: Problem solved.

Well, I called an HVAC guy and he saw my wiring and said it looked right. But he went out and found an exact replica of my old motor, installed it and it's now up and running fine.
The lesson is, if your motor has 3 wires then find an exact replica for it, don't try to use a different one with more wires or slightly different specs.
I must add that my outside unit is very simple. No Starter Relay or anything like that... just the capacitor, fan, compressor.
