OL reading between two windings indicates what?

Explanation:
OL on a resistance reading means infinite resistance, or no current path. When testing between two windings, they’re electrically isolated from each other even though they’re magnetically coupled, so there’s no direct conductor between them. That’s why the meter shows infinite resistance. If there were a short, you’d see a very small resistance; if the windings were directly connected, you’d read 0 ohms.
