If you touch the multimeter probes with each other what reading do you get?

I get 000.0 if i hold the probes together
princess prin prin:
That's zero ohm which would point to a short. OL is the opposite, infinite resistance. So from the previous tests there's no short in the flyback or in the collector line. How did you test the HOT and what readings did you have?

Hi
I tested the HOT (BU2520DF) in my china tester

Desolder the other flyback pin connected to the HOT collector and repeat the tests. Also when you put the probe on the chassis make sure the points are squeaky clean and not covered with flux. Clean with q-tip and alcohol in case. And don't put the tip of the probe in the hole but on the pad or some other points connected to the pad.
