Another Sabvoton 72150 error “lack voltage”

[cvctiger]

I encountered a “lack voltage error on my 72150. I rode the bike for a mile the day before and it was fine. I did knick the motor wire on my QS205 before the ride but there was no sign of a short and didn’t look like it shorted any wires together and no obvious signs. Did a “hall test” in app and it “test ok”. Turned on my bike to ride this morning and this error popped up. I disconnected most everything except for the motor wires/hall sensor and ignition switch. The “lack voltage” was still there. Then while power was still on I disconnected the hall sensor harness and “lack voltage hall sensor” appeared and then reconnected the hall sensor the message was still there..turned off power then turned back on and just “lack voltage” error and led status blinked one cycle red/green….last I want to hear is that the motor wire is done.

low battery voltage settings is wrong or to low in your settings. It can also be a problem with your battery with the symptom of lower voltage.
