So it looks like the transformer is rooted!
Hi Chris,
Hmmmm ... transformers are pretty simply devices not that prone to failure. I'm not familiar with Sterms, but you sound despersate, so a few ideas;
- History of the machine - is it wired for the correct voltage? If it's configured for 110V input then the output voltages will be approx twice what they should
- Remove all connections and just use the meter to measure transformer output voltage - with nothing connectied it should be a bit above the nominal voltage. What is it?
- maybe post a fragment of the schematic of the area of interest and you might draw a few comments and ideas
- test rectifier board into other machine
Good luck.
