How does a meter with a AA or 9v battery blow the terminals off? Is there a new hydrogen/oxygen refrigerant ?
Taking measurements off the leads may cause you to replace a good compressor due to a bad lead or bad connection.
And while your questioning his electrical expertise, I'll question his refrigerant/oil expertise. It's not acidic.

Just keep touching your leads on the terminals of compressors with grounded windings,
It will happen. I don't have much HVAC experience, just a little shy of 40 years .
