There's a
Photon up for sale on eBay (U.S., east coast), and the owner describes issue(s):
- The kit functions as it should with the exception of both brake sensors not working as they should
- When 'brake sensor' is enabled in the CYC app, and BOTH brake sensors are plugged in, the throttle doesn't work and both brake sensors don't register magnet movement ( turn blue)
- When there is just one brake sensor plugged in, the system registers magnet movement to that specific brake sensor- however the throttle still does not work
- I've pretty much been riding this without the sensors connected - on pedal assist and throttle. Both work when the brake sensors are NOT plugged in
- I've been in touch with CYC about this issue and they offered to send a replacement harness and two new brake sensors even though I don't think that's the problem. I personally think it's related to software or firmware but I could be wrong. The first thing I did when I got the kit was update the controller firmware through the app which was successful.
My bet
is the main harness - but it could be in either segment. I find it curious that the seller didn't take CYC up on their offer, and decided to bail after stating it has all of 6 miles riding time. I also feel that the asking price could scare off most risk-takers. But what do I know?
Plugging everything in, then running the App throttle calibrator might give more clues - are the end voltages way off, for example.
I bought directly from CYC, a 1-plug main harness (display only) - no worky. Not much to go on, but it could be that CYC has some questionable harnesses out there.
