So here's a new one I haven't seen before...
Took the bike for a spin yesterday, was giving it some juice, trying to see if i could squeeze some extra power out using OVS settings. I wasn't doing anything tooooo crazy, but I did give it wide-open throttle for about 15 seconds and it got up to 134A.
Anyway, I go around a corner then KA-CHUNK! KA-CHUNK! The wheel is cogging hard, sounds like it's missing a phase. Tried turning it off and on, tried the autodetect, which gave me the error: "Halls E1". Couldn't get it to work on sensorless mode, hobbled the rest of the way back to my home at <10KM/h with loud clunking.
Looking up this error on here and the russian forum and started getting really worried, everyone was saying this is usually caused by a faulty controller. Took a look at it this morning and I found the problem:
It appears one of my phase wires has come loose!
On further inspection, it looks like it desoldered itself from the controller end. This solder hasn't broken, it's a melted glob.
So, that's amusing, but also deeply unsettling. I've never had much faith in these XT150 connectors to begin with, but now I'm actually afraid to use them.
I'm going to solder this back on, because what other choice do I have, but this wasn't my faulty soldering that's the problem. This is the factory installed end. So, I'm pretty uncomfortable getting back on the thing once I fix it.
Has anyone else had phase wires come unsoldered? Can anyone recommend better connectors?
