BHMQ-1 nickel/M3 Lead Color Code

[korneluk]

For the BHMQ-1 nickel/M3 transformer, what is the lead color code (red/blue and black/orange)?
which one are the primary/secondary windings?

kind regards,

[Paul Birkeland]

They should come with a hookup sheet?

Red/blue is usually the primary.  If you use your multimeter to measure the DC resistance of that winding, it should be considerably higher than the orange/black winding, which will measure very low.
