Mine arrived with the blue wires loose in the box!
Ponz
From the manufacturer? N.I.B.????
Or from a secondary market/sale??
If the blue wires were clipped off, I'm not sure what the perpetrator had in mind. IMHO, they won't work without the blue wire....
Connecting to a track relay (e.g., ITAD), the blue would be common, the yellow n/c, the white n/o.
Anyone else have an idea what he's got....for options.
BTW, having repaired/recycled dozens of these, it's possible to replace a wire once the main circuit board has been freed from the base. Not a job for everyone,......but doable.
FWIW, always...
