Hi Bryan good to hear that you have a working inverter.
I read up the page a bit that you had trouble soldering old cable. Often the plastic seems to migrate into the wires. I have found that dipping the end into hydrochloric acid to clean up the cable works well. Just strip a bit back , dip the end into the acid for a short time and wash it off. The cable comes out shiny and easy to solder.
Maybe you had the two windings of the transformer hooked up in reverse to each other. Sounds like the high voltage windings may have been fighting each other to have such a massive idle current.
Anyway it looks like you have it sorted.
I looked at the board you showed on aliexpress, the one ticked was 220 volt 60 hz and 60 volts. I am guessing that is not the actual board you used.
Have fun
Pete
