The manual you attached offpist1 mentions an LED code reference table, but it is not included in the document.
My controller does flash some pattern on the LED, so would kind of be interesting to find out what it means, in case the problem is actually external to the controller...
So if anyone knows about those codes, please let me know.
Otherwise, well, for the right price I can perhaps be interested in the original controller, do you have any idea what you want for it?
I was originally thinking I wanted something more robust and potentially better performance, since it seems from what I read that these controllers break quite easily.
But of course just replacing it with an equivalent is a lot easier...
I am not interested in another complete scooter, actually I was not planning on keeping mine either in the long run.
