AC Voltage Through Frame/Stablizers

I went through the AC unit and tested a few things and believe the issue is within the wire, not the unit. I returned to the breaker box and did not see anything obvious. But, it did appear the clamp which holds the wire into the box was on quite tight, pressing into the wire. It did not appear damaged but clearly squished. I cut the foot of wire off and re-wired it and seems to have solved the issue. There is still no obvious damage to the wire, but no more voltage issues, but I will keep an eye on it.

Thanks all!
