The white conductor is usually for the speed sensor. It shares the same 5v and gnd as the rest of the halls. The side cover will usually have the corresponding magnets. You can trace the white conductor to locate the sensor, which would physically line up with the magnets when the cover is on.
Looks like some moisture made its way in, but not many other signs of that. There is some crud down Ethen the magnets and hub housing, so maybe it was leaking around there.I'm not liking the look of what appears to be rust on what looks like some resistors.
Nice that the manufacturer labeled everything. The white wire might be your speed sensor.
I’m starting to imagine something that’s different than the standard julet/higo. Too there aren’t any pics.Ananda seems to have a different wiring than standard 9 Pin Jullet/Higo connector.
The phases aren’t the same (have to exchange blue with green).
Question is about the mapping of the hall sensors mapping to the 9 Pin connector (the small wires white, blue, yellow and green). Ground (black) and +5V (red) are 1:1 mapped.
