I had to cut some wires to remove my heated pitot pobe and didn't think re-connecting would be a problem since the manual shows all wiring color-coded. Unfortunately coming from the probe, I have: 2 18ga black wires, 2 18ga white wires, and 2 very thin white wires . So instead of a blue and orange wire coming from the probe as described in the manual, I have 2 white wires with no markings. The 2 black wires are surely ground, and the 2 thin white wires are no-polarity sensor wires.
So the question is how do I connect the 2 white wires from the probe to the blue and orange wires coming from the controller? Apparently the probe has 2 separate heating elements fed by the blue and orange wires from the controller. The resistance across each element is about 2.8 ohms.
1. I could apply 12v to each heater element ans see if they draw different current
2. If each element heats different areas of the probe, I could connect them and feel which area gets heated
(options 1 & 2 would still require someone with knowledge of the internal wiring to determine which is which)
3. If I connect the white wires from the probe to the blue and orange wires by just guessing, will the PITOT HEAT STATUS indicator light illuminate when I have the wrong connection and stay off when I have it right?
Any ideas appreciated
