A few days ago my Bionx stopped working. The display went blank and I could not get it to turn on again. I checked my external wire connections and they all looked good. When I tried to hook it up to the charger, the red light on my charger came on, but the one to the right of it did not. It usually goes yellow to green when it is fully charged.
That night I opened up the box and looked to see if any of the wires to the BMS board had come unsoldered. Everything looked ok. I hooked up the battery pack to my voltmeter and it gave me 41.6V (I think that’s normal for a fully charged pack).
There was fuse that was solid colored (you could not see if it had blown). I tried to scrape away the gray paint, but was not able to do so. I replaced it with a new 30A fuse. When I put it in, there was a small but audible “snapâ€.
With the new fuse in, I tried to charge it again and it worked(!). yellow to green when it was fully charged. However, when I attached it to the bike, it would once again not turn on. What do you all think? Do you think I have a bad console display? They are selling some on ebay right now for $100 or so.
There is a small empty slot on the charging port, but I can’t see a corresponding wire that should go in there:
A word about this Bionx unit: it is about 3-4 years old. Out of warranty. I don’t have a lot of miles on it. Probably less than 1K. I only use it in the summer, when it gets too hot to ride my regular bike and I don’t want to get to work all sweaty. I have removed the battery pack in the winter and stored it in my room so it won’t exposed to cold weather outside. Haven’t let it be fully discharged.
Be happy to answer any questions. Thanks in advance.
