multimeter  checking process:

OK: one side high value and other side low value or one side value and other side Nothing

Damage:one side value and other side Buzzer or Both side buzzer .

Compare to ground : ground to emitter buzzer (NPN) or both side to emitter high value or both side to collector low value
