Hi all
First time posting here. Excited to learn from the wealth of knowledge in this community!
I have a Yuba cargo bike that I converted 3 years ago. I added a bafang mid drive (BBSHD) system and it has given me endless joy and utility. A couple months ago, i encountered a strange symptom where in the middle of my ride, the motor started to "stutter" (cutting in and out rapidly) and the display indicated that I was out of battery, even though I had 75% charge left on it. The system then shut down completely (motor + display) and I could only get it to start up again after letting it sit for a while. But I quickly encountered the same issue again and again.
After much tinkering (taking the motor apart, buying a new controller, testing the battery), I ended up finding the problem in a place where I obviously should have started: the brake sensor. Once I unplugged *one* of the brake sensors on my more-recently installed Tektro hydraulic brake, the bike works now works beautifully.
My question: How can I be sure *where* the problem is occurring in the brake system. I've purchased a new 3-pin sensor cable that feeds into the brake lever, but if the problem is occurring elsewhere, I'd rather not go through the trouble of installing it. Any advice??
