Danny... bad news... I may have killed another speedict
Here is what happened:
- I connected as usual the speedict to the battery and controller, no problem.
- Then sliced the temp sensor. I connected the white wire (signal) to the temp sensor coming out of my mac.
- For unknown reason, just with this white wire, the speedict was able to read the temp! Miracle. It reads 26.5C. Perfect.
- I tried to use the throttle to see how the temp would increase... I started slowly... then go faster on the throttle... The wheel spins and I was looking at the temp.
- But it didn't stop. The wheel keeps spinning!
I thought it would be a problem with my throttle wire, I disconnect them one after the other... Red, green, black... No more throttle connection.. but the wheel keeps spinning at max speed.
-- WHAAAAat the fuuck?? Motor keeps running without throttle connected at all????
- It started to smell the melted plastic. Damn!
- While handling the bike, I used my leg and unplug the main wire of the battery. Everything stops. Wires are all hot. And speedict stopped working. There is only a very dim green light on it...
- When I plugged again the controller to the battery without speedict, everything works as normal. Motor doesn't spin automatically and spins only via throttle.
I don't understand what happened. It looks like a windows bug. Usually ebikes are very predictable. It seems like there was a short or something that used max amps somehow via the temp sensor... Speedict was only connected via the main wires and from the white wire of the temp sensor. I don't see how anything can short..
