Hi all, newbie here, so I may make mistakes. Sorry.
I have read stickys, but question not answered.
A year ago I bought an Alfawise X1 bike from Gearb*st.
It ran once round the block then the motor would hardly turn on assist or throttle.
I checked the battery in and out of bike and it's showing a healthy 42v (and this was after about 10 months sitting, charged inside the bike) it's a 36v 10.4 ah.
After a year of trying to get the bike returned to them, with no luck, I decided to give it a go. I do have basic electronic testing equipment, being an electrician Fluke MM, clamp ammeter, and so forth.
The controller is a X863-AA005 250w 36-48v current limit 12a.
I cannot find the same for love nor money, and to make it more complicated it has a 6th wire (white) in addition to the other 5 on the hall plug. Why is that? What does it do, if anything I should be concerned about?
I saw the excellent spreadsheet and am quite prepared to go through the process when testing to find smooth acceleration coupled with low current draw.
I'd be more than happy to supply detailed photos of the cables, and also the internals of the controller, to show where the cables terminate
One last question: I have seen a controller advertised on Banggood that works in dual mode in that it will work without hall sensors. Would that intefere with the process of working through the spreadsheet?
TIA
