I have two old transformers that appear to be fine, however no DC voltage was measured on the secondary coil.
I have measured:
The input voltage: 229 AC
the input coil ohms: 0.015 kOhms
the two parallel output coil ohms: 0.008 kOhms each
the multimeter base resistance when i touch the probes = 0.006 kOhms
resistance between AC and DC coils – no continuity.
The other transformer is similar, continuity between the primary and secondary, AC 230 in, DC 0 out.
What kind of problem affects both these transformers?
