Hi there,Hi RichB . I have been following your thread with interest. I appreciate it will be very frustrating and annoying to you but wonder if I may ask a question out of curiosity?
Whoosh suggested a broken wire. I know very little about ebike batteries but the thought had also occurred to me so I’m interested to know if B14+ back ro the BMS has good continuity. Did you check the wire from its connection to the cells back to the BMS? No loose connections, dry solder joints or hidden breaks under the insulation sleeve?
Yes a broken wire was certainly a possibility but I’ve actually taken a reading directly from the last cell group as well and that is also showing zero volts. For some reason the last cell group has drained down to zero and nothing I’ve done so far has been able to put any kind of charge in it.
