Help please With Bike
Hey everyone,
I’m troubleshooting a front hub motor failure on a Maxfoot MF-19 and hit a technical wall tracking down component specs. After tearing things down, I found two clear issues on the boards.
1. Internal Motor PCB (Hall Board)
The Issue: Inside the hub motor, surface-mount capacitors C1 and C5 are completely missing, leaving behind scorched pads.
2. External Speed Controller
The Issue: A wire has torn completely clean off its main solder pad in the wiring harness bundle section.
for the empty pad and the surrounding layout.
Current Symptoms
The motor currently just makes a try to do sum then dosnt do anything
My Questions for the Experts:
Capacitor Specs: Does anyone know the exact voltage and capacitance values for C1 and C5 on this specific internal motor board?
Controller Wiring: Does anyone have a diagram or a matching controller to help identify which color wire belongs on that empty pad?
The Cascade: Is it likely that the blown caps on the motor board caused an overcurrent event that literally desoldered/popped that wire off at the controller?
I have a multimeter and am comfortable with SMD soldering, I just need the right part specs to patch this back together safely. Thanks in advance for any insights!
