My frame shows 85 volts.

Two days ago I went riding and it started snowing. My bike was outside, and when I got to it a few hours later... the wheel stuttered. First though: water got into motor and halls died.

Later that day when bike was dried up, it worked.

Skipping to today...
I went riding in the snow and after finishing and letting the snow melt off the frame I went to see if it works. ...wheel stutters again.

Though: Hall sensor must have died? ... but I did even less riding in the snow than I did two days ago... so it must be something else (but related to the halls, phases... or something)

I inspect the (wet) wiring harness going into the motor and find that it shocks me when I touch the frame too.
I measure the voltage across the the shield of the wiring harness and frame to find:


I'm puzzled as to why the wheel stutters and wiring harness to frame is 85V (my battery shows 92V).
Willing to bet as soon as it dries up, it'll work again.

Edit: Continuity test:
-battery + to frame is 0 ohms.
-Wet wiring harness to battery - ... no reading, probably because wet wiring harness isn't conductive enough.

don't ride it until you fix it....you most likely have a phase wire that is shorting to the dropout.

6 hours later (now) the bike is dry and I checked if the wheel spins.. it does.

A phase and hall wire near the drop outs were taped up after a crash a couple weeks ago. I'll look into insulating those within the wiring harness better in case it was there that the water made a conductive path from it to the frame.


..........but I don't know where battery (+) could possibly be making contact with the frame.

Edit:
Disconnected phase wires and problem still persists. Feel a tingle from wire harness to metal frame using one hand.
...might be hall wire letting the current pass.

Edit 2:
Found the green hall wire to possibly be responsible for this (90% sure). Cut in the insulation under the area I once repaired.
Now if only i knew why/where the frame is connected to Battery (+)...
