A +ACI-megger+ACI- is a meter so he means he checks the
winding resistance ... what's a kegger?

Specifically what Tony did used high megaohm tests w/ high voltage
potenial at very small current across a two pin that connects to each
winding (between turns leakage and winding and the core) for leakage.
Insulation on windings go bad with age and use.
