Hi guys, new to the forum, thankful for any help you might be able to give
I'm trying to fix a BH Bikes Emotion that had unrecoverable error 13. I have replaced all the electronics with generic components from eBay, as there were no spares available from BH Bikes on any website I could find. I bought an S866 display with "20A" no-name controller together as a kit, and installed those. At this point I discovered that the bike does not have a PAS, but rather a torque sensor in the rear mech hanger. The generic controller does not have an input for this signal - hooking it up to the PAS input just gives an error - so I bought an S-V12 PAS and connected that up.
I can get the motor to spin to full speed using a thumb throttle, and it also work correctly in walk mode. However, I can not get PAS to work properly at all. The best I have achieved is brief pulses of power when rotating the cranks *very* slowly. This is with PAS sensitivity set to 1 and PAS level set to 5. Any other setting produces no motor output at all at any crank speed, and moving the cranks at any normal speed produces no motor output with any settings. The red light on the sensor flashes correctly 12 times per revolution and the controller is set for a 12 magnet sensor. Driving mode is set to "PAS and throttle".
Since these are all brand new parts I'm not expecting anything to have a fault, but I can not work out what the heck is going on. Has anyone got a bright idea?
Thanks in advance, Matt
