No, that's all there is on the secondary side: four diodes and a
capacitor.

The primary side should be around 2,000 ohms (wide variation)

The secondary side should be around 10 ohms (wide variation)

If no continuity on either it's toast.

But the OP reported low voltage. A transformer is like being
pregnant: either you is or you ain't. As you point out, either open
or not. If open, zero volts. How do you get 2 volts?

I wonder if the OP was measuring correctly. (Don't laugh: the other
day I measured something with a very low voltage; turned out I was
trying to measure an AC source with my (analog) multimeter set on DC.)

It's real easy to measure an erroneous voltage with a DVM...phantom
voltage.

Explain "phantom voltage", please. Never heard of it.

Sounds scary.

A high impedance meter will often pick up a few volts out of the air.
Place one probe in a live wall outlet without making a complete circuit
and you'll likely see a volt or two on the meter.

Aha, so it's a matter of high sensitivity to ambient EMF. Gotcha.

I'm glad I still have my trusty old analog VOM.
