Fan and compressor not turning on...blowing breaker
internal AC unit kicks on but blows warm/hot air. Outside unit starts to kick on but trips breaker. Neither compressor nor fan come on outside. Fan turns fine and compressor continuity checks out fine. I look at the “clips” from the fan to the capacitor and I see the yellow wire “clip” looks burnt. Thinking this may be the issue. Should I replace the motor/wiring or just try to replace the “clip” from the fan to the capacitor? I have pics if anyone can help. Thanks.

Welcome to the forums.
Clips ? Crimp terminals ?

If the wire connector to the capacitor is melted I would replace the connector and the capacitor.

I replaced the fan motor, but same thing happens. I unplugged the wires to the compressor and then turned the system to cool. Breaker doesn’t trip. My guess is that the compressor may be bad. What is the best way to check for a short to ground?

Please, don’t replace parts unless you’ve determined they are defective. Doing otherwise is a waste of money.
Use your meter to check for shorts to ground.

compressor continuity checks out fine
You need to check between the three contacts. Your meter needs to be set to a low scale like Rx1 ohms. You should measure in the area of 5 to 15 ohms. 0 or close to 0 is a short. You need to check from each terminal to ground. There should be no continuity from any terminal to ground.
When working on a compressor. Do not put your body or face near the connection plug while removing the wires from the terminals. That plug can become weakened from the heat and can launch out of there under high pressure. Needle nose pliers should be used to carefully remove the wires. Safety glasses MUST be worn.
