I brought my batteries inside to warm up, then tried charging with the QuiQ 96v and adapter. Not working, charger just reads fault no matter if hooked to batteries or not. I know the 3.3's are charged up, and believe the 2.6's are? This all started when I plugged both bikes into one circuit, which I now know is not recommended. The temp plummeted and while out shoveling I noticed the FX was not charging and would not even power up. I tried onboard along with QuiQ but nothing happened. Then I pulled the FX batts and put the FXS batts in the FX. It powered up and was registering a fault 21 which I guess is a contractor error. I will have to wait till it warms up a little (currently 1 degree) then I can run my garage heater and try putting the FX batts in the FXS and see what the status and see if they will charge. I still don't get why they won't charge out of bike with the QuiQ by itself. It is brand new!
