[time-nuts] Ault SW-305 wiring colours

[John Nelson]

I bought a Thunderbolt via TAPR some time ago which came complete with an
Ault SW-305 PSU. For some reason I can't find the documentation that came
with it and don't have the wiring colour codes. A diligent search of the
internet hasn't thrown up anything -- can any kind soul please assist? 

There are six wires emerging from the supply: red, brown, green, black,
white and blue. I seem to recall that red is +12V and black is -12V but that
leaves four wires for one rail and ground...
