Finally got the battery apart with the dead module reading. Attaching image of the software reading before disassembling. Module on bottom of battery acts as if it was not in there as software shows. Took apart and found a little moisture in the bottom of the cover. Popped off the module cover and saw some interesting stuff. Pack reads 61.2 volts. I did also test from main connection but only got 1 module reading. I'm not confident in going any further than this. Also, thought I'd see all modules voltage combined but not seeing that. .. So, @OneLapper or @Mark911 or anyone, any ideas? Owner wants to get back on his Alta!
