All connections look tight. I'm thinking a drain and reset is a logical next step.

Hi all, my battery took a pretty nasty tumble, after which it only seems to be putting out 40.7 volts, as opposed to the spec'd 48. When I jump the internal leads, it shows 51+ volts, so I'm guessing the board has suffered some trauma, (see pics). Any thoughts on next steps would be greatly...

Problem solved. Replacing that second hall sensor did the trick. Thanks for all the excellent, thoughtful advice. This forum is awesome!

I think I may have cracked it. In the absence of a schematic, I was operating under the premise that the phase wire colors corresponded to the sensor wire colors location wise, which it turns out is not the case. After more probing with the multimeter, I realized that my initial assessment of...

But if the signal is toggling at the hall sensor but *not* at the signal output point to the controller, there *has* to be a connection problem that causes such a high resistance between that point and the sensor that it's able to drop the whole 5v across it while the hall is grounding the 5v on...

I knew that old 5v wall wart would come in handy one day. In your face, better angels of not-hoarding old electronic junk! Anyway, here's what we got without the controller: 5v going out to all the halls, but nothing coming back to the pad. 5v at the white wire, but nothing else. Continuity (but...

Awesome. Thanks so much! I've already done all the common sense continuity/short tests, so it seems to make sense to rule out the controller next. Since the power flows through the controller to the motor, I assume a small battery like a 9v is the appropriate power source?

Hello All, Newbie here Looking for some troubleshooting advice. I've got a brand new Bafang front hub motor that spun out of the front dropouts, damaging the wiring harness in the process and resulting in the dreaded error code 8 coming up. After much poking around on the interweb and pointless...
