I am thinking that if I have 5 wires (2 for wind speed and 3 for wind direction), I might be able to determine the wire groupings using continuity testing!

My understanding is that the wind speed is calculated by a simple magnet in a coil - as it spins it will generate a current (simple dynamo?) which the display translates into knots!

By elimination the remaining 3 wires are for the wind direction and I should be able to detect which is which (power or ground) from the resistance reading (worst case might get it pointing wrong poles!)

Not sure if this makes sense - will need to try it out!

It would seem that the manufacturer would have a schematic and save you the trouble. No luck?

No luck with NASA but it could be because of the holiday season! I will give them another nudge next week.
