Hi Endless Sphere,
After years on back burners etc I have finally reached the point of trying to turn on my bike and I can't figure out why I keep getting error code 4,2 from my Kelly controller KEB7238. I have it connected to a Cyclone 7,500w motor. I've verified that the hall wires are connected as directed by Cyclone and all connections are good. I also have checked in the program that I've set it for 120 degrees on the Hall- not 60 (again per Cyclone's instructions).
I was looking around on this forum for others who had this issue and found one where Fetcher was suggesting to someone that they may have a bad ground (if I'm interpreting correctly). I'm pretty illiterate about all this kind of stuff and this all makes me wonder if I have the thing grounded correctly. At the moment I have the negative battery terminal going from the battery to the B- on the controller. Should that also be connected to the chassis, kinda like you'd find in a normal gas powered auto?
I'm worried that I have charged my lithium ion batteries to full and have no way to discharge them now.....
Any suggestions would be much appreciated.
The attached photo is from around October of 2018 - before I finished the battery box and mounted the controller etc. I included it just so you can get the idea of what I'm building. I was inspired by the French guys doing LMX. I want more power though....
Thanks,
Stefan
