Riding home from the store today my bike lost power with in site of my house. I've been having trouble with my shitty crimp jobs on some andersons, so I just took it home.
I plugged it in and all the cells were growing red, but the battery still was not putting out power.
For some reason I thought maybe it was the diode, and it appears I was correct about this. The voltage at the main pack was 29, but before the diode it was a normal 58. So I think great, I don't need a diode. I'll just turn my regen braking system off. I wired the two thick red and black cables to the controller, and the thin blue and red to a new charger input as per http://www.pingbattery.com/usrguide/Wiring%20Guide%20V2.5.pdf
The bike works. Maybe even a lil' peppier for lack of the diode. However now the charger won't work, when I plug it in to the new connection. The charger does charge the battery when I briefly plugged it into the controller connection as a test.
What's going on here? Why did the diode fail in the first place?
Also for your judgment is a picture of the bms. The far right mosfet (I think...) Is covered with burned up duct tape. I measured the voltage between each leg of the 5 mosfets. They all read ~14 except the far right one. Could this be a cause?
