Which transformer?
You only show half, which is same as nothing.
Please post more complete schematic.
No guessing allowed on mains circuits.
Besides:
1) what´s wrong with connecting mains the proper way, straight at "K001 - Power In"?
2) I hope you are not inserting both jumpers J001 - J002 at the same time,it´s either one or the other
3) disconnect all secondaries (half) shown: at K25 and incomplete/not shown connectors under it
Much suspect your shining lightbulb comes from a secondary load problem, rather than transformer itself or its primary connections.
Even if not, let´s separate them for confirmation.
